disconnection every game. unacceptable, FIX THIS EA

Ok this is crazy guys, since the last patch it is impossible to play rivals in co-op with my PC friend. 

We tried everything: last year there was this "bug" where if you used more than one custom tactic, the game would crash INSTANTLY. i know its crazy, but they do this, not me.

now this, if we try to play friendly or the silver cup, it works. no crash, nothing, we can play til the end. but if we try Rivals, he crash after 13, 30 minutes, not important. even after half time.

so, i know the problem is on PC but i would like to play with my friend so whats so hard about fixing this? you know thats not a FUT problem but its only Rivals and Rush, you know thats not a Co-op problem but a PC/Xbox only.. SO WHAT ARE YOU WAITING FOR? 

you work on the game and suddenly you dont know how to revert something you did?? thats embarassing. i hope you fix this ASAP because all that lies about listening to the community ecc ecc are already ridicolous.
