I got a crash while trying to run Yabba on my server. I'm pretty sure it's caused by the registration of models on the server-side.

I am also receiving this error while trying to launch a server with YABBA.

Same error, seems to be client-only mod so far.

Does http://mods.latmod.com/YABBA/1.10.2-0.1.1/ fix it?
