MixinTrace Mod adds extra details to Minecraft crash reports. When the game crashes because of mods, it can be hard to tell which one is causing the problem. This mod adds a list of mixins to the crash log, which helps developers and players quickly find the source of the error.

Frequently asked questions

How do I know MixinTrace is actually working?
Trigger a crash or force one, then open the crash report and scroll past the stack trace. If the mod is active, you'll see an extra section listing mixins and their configuration names near the bottom of the report.
Where in the crash report is the mixin list?
It's appended after the normal crash report content, usually under a heading that mentions mixins or mixin trace. Scroll to the very end of the file rather than reading from the top.
Does MixinTrace work on its own, or do I need another mod?
It works standalone. It hooks into the crash-report generation itself, so you don't need a separate crash-log mod for it to add its mixin listing.
My game isn't crashing — can I still see the mixin list?
The list is only written when a crash report is generated. If nothing crashes, there's nothing to read, so you'd need to reproduce the failure to get output.
