How to reproduce

launch mixin compatibility and baritone together and experience the crash

also note that this was found when testing to see what caused rlcraft to crash with baritone, and we also found that phosphor requires mixin compat to work with mixin bootstrap which is in rlcraft so you need to remove mixin compat and phosphor if you want to use baritone with rlcraft

Final checklist

• I know how to properly use check boxes
• I have included the version of Minecraft I'm running, baritone's version and forge mods (if used).
• I have included logs, exceptions and / or steps to reproduce the issue.
• I have not used any OwO's or UwU's in this issue.

would you mind elaborating it here on how that is possible without changing the source code?

reason found. mixin compat doesnt like the notch-mapped refmap

Iirc you can add

reobf.jar.mappingType = 'SEARGE'

to the build script and do a normal build with that.

is there really no other way than to remove mixin compat? (which crashes rlcraft)

You'd need to make yourself a srg mapped Baritone jar.
