I have all the necessary mods to run the Too many Origins, but we cannot activate the mob effects on a server setting. I'm not sure if there is something in the mod that is preventing it but I thought I would let you know.

Alright. Both of these abilities have been fixed in 0.1.1.
Status Effects should not have any issues unless compatability problems exist if you meant that.

May I have server logs and mod list?

Okay, I've replicated this with Rocket Jump (crashes the server) and Draconic Breath (doesn't work) if you meant abilities.

I'm wondering if you meant status effects by saying mob effects and if so I'll look into those too.
