Debug Worldgen Crashes When This Mod Is Active

Reading Mod Logs for Worldgen Issues

Even with Worldgen Feature Fix Mod installed, some data pack configurations may still cause problems. The mod logs detailed information about which features it processes and which ones it corrects. Use these logs to identify the root cause of remaining crashes.

How to Diagnose Issues

1. Check your latest.log file in the .minecraft/logs directory

2. Search for entries from Worldgen Feature Fix Mod—these show which features were processed

3. Look for error messages that describe specific feature names or configuration problems

4. Note the feature type (water lake, snow, freeze, etc.) that's causing issues

5. Review your data pack's JSON for that feature—check syntax and required fields

6. Test with a simpler pack to isolate whether the problem is mod compatibility or pack configuration

The mod fixes many crashes automatically, but cannot correct fundamentally broken feature definitions in your data pack. If crashes continue after the mod processes features, your pack's JSON likely has syntax errors or missing required configuration fields that need manual correction.
