Hey!
I recently got a bug report, from the looks of it my mixins fail. I wasnt able to gather much from the log, but from the looks of it I think Moonlight API seems to be using a class that isnt available on all systems.
error.txt
I may be wrong, but Im hoping this error means something to you!

I have no idea. First that class it mentions is included in a library used by the game, second I'm not even using it. Maybe it's something with quilt

This issue has been resolved on my end!
