Troubleshooting Remapping Failures and Crashes

Reading Remapping Errors

When a mod fails to remap, the game log contains details about what went wrong. Look for messages mentioning specific mods, missing classes, or mapping mismatches. These clues help identify whether the problem is a remapping issue or something else.

Common Causes

Remapping fails when a mod uses internal APIs that don't exist in your target version, relies on hardcoded version checks, or contains obfuscated code that can't be safely translated. Some mods simply aren't compatible with certain game versions, regardless of remapping.

Testing Mods Individually

Add mods one at a time and launch the game after each addition. This isolates which mod causes crashes. If a mod works alone but fails with others, there may be a conflict between their remapped code.

When to Disable Remapping

If a mod is designed for your exact game version and loader, remapping may be unnecessary or even harmful. Check if the mod's documentation recommends disabling remapping for your setup. Some mods include their own compatibility layers that conflict with automatic remapping.
