I love this mod personally and I would like to report a issue. You know orespawn it has a lot of cool mobs I want to play as but for some reason in the console says something about the ability to swim and if you kill any mob it will crash even if it is not from orespawn. Also just a suggestion I think a spider's ability should spit out a web wherever the pointer is pointing at and bats when they are against the ceiling I think they should hang on it, just 2 suggestions and a problem!

Could you pastebin the crash log?

Hm, I'm unsure about those two abilities, though. It might be fun. I'll think about it.

Closing the issue due to lack of reply.
