Great mod! It's really fun and I play this with my friend all the time. There's some bugs, however, and some are the same ones many have been getting:
Renderman spawns while disabled without his light, and he's safe to look at and doesn't chase properly, eventually vanishing.
The console constantly displays error messages saying that his sound files cannot be played when he's disabled.
Renderman Detector tool's readings aren't always accurate, like when you're not looking at him but you're right next to him. I went in 3rd person to check if I really was with him, but it still won't correctly display the readings, not even if I touch him.
Fix these and I'll be happy!

Or, if you can at least tell me how to stop him from kicking ppl besides the host. My friend knows but he refuses to tell me.
