Issue Description
Read the title.

latest.log

Looks like several other mods are loading Mixin which is causing a conflict with MixinBootstrap, Removing MixinBootstrap should fix the issue.

A mod requires this to be used with it.

Well, this mod crashes with no reports being given. So even without that, same thing happens. Crash with no report.

Can you upload you're debug.log file, That will contain the crash information.

That mod should still function fine as another mod is providing the Mixin Library.

Closing due to no response.

The solution to this issue is to remove MixinBootstrap as Mixin is being loaded by several others mods.
