First off where is there a ticket submission if there is one?

So my friend and I have been playing coop mode from the very beginning. We are both level 15 now and every time he joins the two characters that he plays stats are completely screwed up. I am the host and when I look at his characters stat screen everything is ok on them but when I give him control of them many attribute points are severely lowered, skills points lowered, some to zero and traits get removed. We only just noticed this happening so I don't know how long its been happening but the first couple times we saw it he rejoined and it seemed to fix it but now it happens every time he joins the game. This makes the game pretty much unplayable as his characters are reduced to the power of a level 5 or maybe even less; besides the fact that no one wants to play with glitched out nerfed characters. What can we do to fix this? Id submit a ticket but I don't know where to do it. Thanks.
