Hi,
it give a Compatibility problem from your mod with the other Mod "Simple Voice Chat" Version 2.4.10. Please fix it I can not play with your mod and the other mod.

Seems like this is caused by this dependency and bumping it to 0.8 should fix this and likely not cause any other problems.

I have this Problem fix with a Mixin Mod what the old and the new version check and workable make. But the Looks mod Creater have her mod site 3 Years so and he build not more on this Project what very sad is

The owner of the "Simple Voice Chat Mod" have say the Problem is in your mod. Please update your outdated mixin version for work with other mods please.
