Common BTD6 Modding Errors and How to Fix Them

Modding Bloons TD 6 (BTD6) on PC can unlock a world of exciting possibilities, but it’s not always smooth sailing. This guide will help you troubleshoot common modding errors and get your game running smoothly again.

Essential Tools:

• MelonLoader: The primary mod loader for BTD6.
• BTD6 Mod Helper: An API that many mods rely on.

Common Errors and Solutions

1. Game Won’t Launch

• Issue: The game fails to start after installing MelonLoader or mods.
• Possible Solutions:
  • .NET Runtime: Ensure you have .NET 6.0 or higher installed. MelonLoader requires it.
  • MelonLoader Installation:
    • Run the MelonLoader installer as Administrator.
    • Try reinstalling MelonLoader.
  • Conflicting Software: Close any cheat software or trainers that might interfere.
  • Corrupted Installation: Verify the integrity of game files through Steam or Epic Games Launcher.
  • Special Characters in Path: Make sure the path to your BTD6 executable doesn’t contain special characters (dashes, accented letters, etc.).
  • Too Many Mods: If you have a large number of mods, try disabling some to see if that resolves the issue.
  • Outdated Mods: Game updates can break mod compatibility. Ensure your mods are up-to-date.

2. “Failed to find MelonLoader bootstrap”

• Issue: The game displays this error and refuses to launch after a failed MelonLoader uninstall.
• Solution: Manually delete all MelonLoader-related files and folders:
  • MelonLoader folder
  • Mods folder
  • Plugins folder
  • UserData folder
  • UserLibs folder
  • dobby.dll
  • notice.txt
  • version.dll
  • You may need to reinstall the game afterwards.

3. “Failed to apply BloonsTD6 Mod Helper patch(es)”

• Issue: BTD6 Mod Helper fails to apply its patches, often resulting in a broken monkeys menu, invisible monkeys, and a missing “Mods” button.
• Solution:
  • Incompatible Mod Helper Version: Using the latest Mod Helper with older game versions can cause this. Update your game through Steam/Epic.

4. “Could not load file or assembly ‘Assembly-CSharp, …'”

• Issue: MelonLoader didn’t install correctly.
• Solution: Reinstall MelonLoader with your antivirus temporarily disabled.

5. Game is Not Saving Progress

• Issue: Your game progress isn’t being saved after installing mods.
• Solution: Ensure you have BTD6 Mod Helper installed and that Btd6ModHelper.dll is in the Mods folder.

6. Mods Not Loading or Working

• Issue: Mods aren’t appearing in-game or aren’t functioning as expected.
• Possible Solutions:
  • Installation Location: Make sure mod .dll files are directly inside the Mods folder, not in subfolders or archives.
  • Mod Dependencies: Some mods require other mods (like BTD6 Mod Helper). Ensure you have all necessary dependencies installed.
  • Mod Order: In rare cases, the order in which mods load can matter. Experiment with renaming mod files to change the load order.
  • Outdated Mods: As mentioned earlier, game updates can break mods. Check for updated versions.
  • Log Files: Check the latest.log file in the MelonLoader folder for specific error messages related to individual mods.

7. Anti-Virus Interference

• Issue: Anti-virus software might delete or interfere with MelonLoader or mod files.
• Solution: Add the BTD6 game folder and MelonLoader folder to your anti-virus exceptions.

8. “Game versions are not compatible”

• Issue: This error usually arises if the game version and the mod versions are not compatible.
• Solution: Ensure that your game and mods are up to date.

General Troubleshooting Tips

• Read Mod Descriptions: Pay close attention to installation instructions, dependencies, and known issues in the mod descriptions.
• Check the Console: The MelonLoader console can often provide error messages that pinpoint the problem.
• Test One Mod at a Time: If you’re installing multiple mods, try adding them one by one to identify any conflicts.
• Seek Community Help: The BTD6 modding community (Discord servers, forums) is a great resource for troubleshooting. Provide detailed information about your setup and the error you’re encountering.
• Reinstall: Sometimes a clean reinstall of BTD6 and MelonLoader is the best solution.

By following these tips, you can overcome common BTD6 modding errors and get back to enjoying your customized Bloons-popping experience!
