Steps to recreate. So I was trying to speed up my fps on a modpack, and I added this mod it loads. But when I joined the server it threw a mixin crash.

This will have to be fixed on Snow Real Magic's end, as it's using mixins to access Sodium internals, which is not stable and could break with future updates, as happened here. I've added it to the incompatibilities list for posterity.
