## How to reproduce
launch [mixin compatibility](https://www.curseforge.com/minecraft/mc-mods/mixin-0-7-0-8-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](https://www.curseforge.com/minecraft/mc-mods/phosphor-forge) requires [mixin compat](https://www.curseforge.com/minecraft/mc-mods/mixin-0-7-0-8-compatibility) to work with [mixin bootstrap](https://www.curseforge.com/minecraft/mc-mods/mixinbootstrap) which is in rlcraft so you need to remove [mixin compat](https://www.curseforge.com/minecraft/mc-mods/mixin-0-7-0-8-compatibility) and [phosphor](https://www.curseforge.com/minecraft/mc-mods/phosphor-forge) if you want to use baritone with rlcraft
