Crashlog changes depending on whether other Mixin using mods are loaded or not. Turning off all other Mixin mods results in the following crashlog: Crash without other Mixin mods

Turning on any other Mixin using mod, whether it loads the Mixin itself or through MixinBootstrap, causes the crash log to point at that mod rather than Apotheosis or MixinBootstrap.

Loading without any Mixin mods other than MixinBootstrap is fine. Loading with all other Mixin mods besides Apotheosis is fine.

I know this says it's closed, but one of the known issues is between apotheosis and quark oddities since they both change the enchanting table in some way

@Irritumerus you can disable the matrix enchanting in quark.

That's probably an issue caused by whatever mixin is messing with that code, as nothing in apoth touches render code.
