Trying to join friend's server, crashing upon trying to select class

[engelsbeardlaser]

I'm trying to join my friend's server and the game repeatedly crashes upon trying to select my class. Specifically, when I try to switch away from commoner, the game crashes.

The server had a few mods. They should all be named in the report below.

Anybody know what the issue is/how I can fix it?

Here's the report:

Turns out it was a conflict between the More Classes mod and Combat Overhaul. My friends and I tried to fix it but we ended up (partially through our own blunders) needing to fully restart from the beginning LOL
