Issue Description

I'm trying to install Phosphor and Lithium, which requires MixinBootstrap for 1.15.2, but when I put the mod into the mods folder and start up minecraft it instantly crashes with exit code 0. I've tried with no other mods installed yet it still crashes, any idea why? Thanks!

This issue was fixed in v1.0.3, However you can simply remove MixinBootstrap as the Mixin library is included by Forge.

Thanks! So I tried it with no other mods, and it does work, but when I put the mods in, it crashes when starting a singleplayer world. Any idea why? Thanks!

Looks like a compatibility issue with Lithium and Performant

Remove Lithium as it's no longer being updated.

Yep, that fixed it, thank you so much!
