Lethal Labs False Boss Icon - Fortnite Bug Fix Guide

📅 Published: 2026-02-06 🔄 Updated: 2026-02-06 👥 Reports: 5 ⚡ Severity: 🟢 Low

🎯 Quick Answer

The false boss icon near Lethal Labs is a confirmed map rendering bug; the only current solution is to avoid the erroneous location and report the issue to Epic Games with reproduction steps.

SECTION 1: OVERVIEW

The Lethal Labs false boss icon is a map interface rendering error in Fortnite. This error manifests as a persistent boss location marker on the in-game minimap and tactical map at coordinates near the Lethal Labs Point of Interest (POI), specifically on the hill to the southeast of the main complex. No corresponding boss character, boss medallion, or interactive elements are present at the marked location. The error affects all platforms where Fortnite is available, including Windows, macOS, PlayStation, Xbox, Nintendo Switch, and Android. This issue is documented within Chapter 5, Season 2. The error frequency is classified as common, with consistent reproduction across matches. The severity impact is minor, as it does not cause crashes or gameplay disruption but provides incorrect tactical information. No specific error codes are generated by this bug.

SECTION 2: SYMPTOMS

The primary symptom is a persistent and static boss icon rendered on the in-game map interface. The icon appears at a fixed geographic coordinate on the hill southeast of the Lethal Labs POI. The icon remains visible throughout all match phases, from the pre-game lobby until match termination. No boss character model, health bar, or associated AI spawns at the location. Interacting with the marked location yields no boss medallion loot pool items. The map marker does not respond to player proximity and does not disappear upon investigation. The tactical map and minimap both display the erroneous icon simultaneously.

SECTION 3: COMMON CAUSES

Category: Game Bug Specific technical explanation: Corrupted or outdated map marker data within the client-side game assets. This occurs when the game's internal coordinate system for boss spawn points references a location that is not populated with the corresponding NPC entity data during match initialization. Why this causes the problem: The map rendering engine draws icons based on a predefined list of coordinates. If the entity spawn system fails to instantiate the boss at that coordinate, the map displays a marker for a non-existent object. Category: Game Bug Specific technical explanation: A mismatch between server-side and client-side game state validation for dynamic events. The server does not authorize a boss spawn at the location, but the client's pre-loaded map data includes the marker. Why this causes the problem: Fortnite uses a client-server architecture where the server is the authority on game state. A desynchronization in what constitutes a valid boss spawn point results in the client displaying outdated or incorrect information. Category: Configuration Error Specific technical explanation: Local game configuration files containing cached map data from a previous game patch or season retain obsolete boss location information. Why this causes the problem: The game client may read from cached data that has not been properly invalidated by a newer patch, causing it to render markers for content that has been moved or removed in the live environment. Category: Software Conflict Specific technical explanation: A conflict between the game's anti-cheat system (Easy Anti-Cheat or BattlEye) and specific memory allocation patterns for dynamic map entities can, in rare instances, prevent proper entity loading. Why this causes the problem: The anti-cheat may incorrectly flag the process responsible for spawning the boss NPC, causing the spawn sequence to terminate while the less-restricted map marker system operates normally.

SECTION 4: SOLUTIONS

Solution 1: Clear Local Game Cache and Verify Files

Difficulty: Easy Time Required: 10 minutes Success Rate: Medium Prerequisites: None Steps:

Completely exit the Epic Games Launcher and Fortnite. Ensure all related processes are terminated via the Task Manager (Ctrl+Shift+Esc).
Press Windows Key + R, type %localappdata%, and press Enter. Navigate to the FortniteGame folder.
Delete the Saved folder within the FortniteGame directory. This action clears locally cached map and configuration data.
Open the Epic Games Launcher. Navigate to your Library and locate Fortnite.
Click the three dots (...) under the Fortnite tile and select Manage.
Click the Verify button. The launcher will download and replace any corrupted or missing game files, including map asset data.

Technical Explanation: This process forces the game client to replace potentially corrupted local asset caches and configuration files with a fresh copy from Epic's content delivery network, ensuring map data alignment with the current game version. Verification: Launch Fortnite and enter a match. Deploy to the hill southeast of Lethal Labs. The boss icon should no longer appear on the map, or the correct boss entity should be present.

Solution 2: Perform a Clean GPU Driver Installation

Difficulty: Medium Time Required: 15 minutes Success Rate: Low Prerequisites: Administrator access, internet connection Steps:

Download the latest graphics driver for your GPU (NVIDIA or AMD) from the manufacturer's website. Do not use Windows Update drivers.
Download and run the Display Driver Uninstaller (DDU) utility from www.guru3d.com.
Boot Windows into Safe Mode. Restart your PC, and during startup, press F8 or use the System Configuration tool (msconfig) to set a Safe Mode boot.
Run DDU in Safe Mode. Select your GPU vendor and choose Clean and restart.
After the restart into normal Windows, install the previously downloaded graphics driver package using the "Custom" or "Advanced" installation option.
Select the Perform a clean installation checkbox during the driver setup.

Technical Explanation: A clean driver installation removes all previous driver files and registry entries that may be causing rendering conflicts with the game's map interface and UI elements, ensuring optimal communication between the game and GPU. Verification: The game's map and all UI elements should render correctly. While this may not remove the specific bugged icon, it eliminates graphical corruption as a contributing factor.

Solution 3: Report the Bug with Diagnostic Data to Epic Games

Difficulty: Easy Time Required: 5 minutes Success Rate: High for issue tracking Prerequisites: An Epic Games account Steps:

While the bug is active in a match, press the relevant key to open the in-game menu (Esc on PC, Options/Menu button on console).
Navigate to the Feedback button, typically represented by a speech bubble icon.
Select Bug as the report type.
In the description field, provide a precise, technical description: "Persistent false boss icon on minimap and tactical map at coordinates near Lethal Labs (hill SE of POI). No boss entity or medallion present. Reproducible every match."
Under How can this bug be reproduced? state: "Launch any game mode. Open map. Observe persistent boss icon at Lethal Labs hill. Navigate to marked location. No boss spawns."
Under Platform, accurately select your system (e.g., Windows, PlayStation 5, Xbox Series X).
Enable the option to Attach screenshot and diagnostic data. This sends crucial log files from C:\Users\[YourUsername]\AppData\Local\FortniteGame\Saved\Logs (or the equivalent on your platform).
Submit the report.

Technical Explanation: Submitting a formal bug report with diagnostic logs provides Epic Games' development team with the telemetry and system context needed to identify the root cause in the game code or asset bundle, facilitating a patch. Verification: Confirmation of the report submission appears on-screen. The fix is dependent on a future game update from Epic Games.

Solution 4: Disable and Re-enable Gameplay UI Elements

Difficulty: Easy Time Required: 2 minutes Success Rate: Very Low Prerequisites: None Steps:

During a match, open the in-game Settings menu.
Navigate to the Game UI tab within the Settings.
Locate the setting Minimap and toggle it to Off.
Apply the settings and close the menu. The minimap will disappear from the HUD.
Re-open the Settings menu and toggle the Minimap setting back to On.

Technical Explanation: This action forces the game's UI rendering system to reload the minimap widget and its data sources. In cases where the error is a temporary UI glitch, this refresh can clear incorrect markers. Verification: After re-enabling, check if the false boss icon persists on the reloaded minimap. This is a diagnostic step rather than a definitive fix.

Solution 5: Configure DNS to Improve Content Delivery Network Connectivity

Difficulty: Medium Time Required: 5 minutes Success Rate: Low Prerequisites: Administrator access on PC or router access Steps:

On Windows, open the Network and Sharing Center. Click on Change adapter settings.
Right-click your active network connection and select Properties.
Select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
Select Use the following DNS server addresses.
Enter 8.8.8.8 as the Preferred DNS server and 8.8.4.4 as the Alternate DNS server (Google DNS).
Click OK and close all windows.
Open Command Prompt as Administrator. Execute the command: ipconfig /flushdns
Execute the command: netsh int ip reset
Restart your computer.

Technical Explanation: Using a reliable public DNS service can ensure proper resolution of Epic Games' content delivery network hosts, potentially correcting scenarios where corrupted or outdated map assets are being served due to local DNS cache issues. Verification: After restarting, the game should download fresh assets upon launch. The false icon may be resolved if it was caused by receiving an outdated asset version from a misconfigured local CDN node.

SECTION 5: PREVENTION

To minimize the occurrence of interface bugs, maintain strict update discipline. Configure the Epic Games Launcher to apply updates automatically. Perform a monthly verification of game files via the launcher's Manage menu. After every major game patch, clear the local cache by deleting the Saved folder at %localappdata%\FortniteGame. Ensure your operating system and graphics drivers are updated on a bi-weekly schedule, using clean installation methods for drivers. Monitor the in-game map for anomalies at the start of each match as a functional check of the UI system.
