I found out that the nature of my CO-OP Issue is a bit wierder than i thought at first. It´s not that player 1 is getting EXP and player 2 isn´t. The problem is that player one gets the EXP of both players. thus player 2 get´s nothing. i dont know wether to call this bug for a bug or an exploit, but it´s insanely unbalanced either way.

Great mod tho, love the idea, this mod is essential :D
