So I didn't have the required DLC to play co-op with my sister (who bought the Dog Outfit DLC) and I parted with some MS points to join a game with her. Fine. Next, I try and join a game with another friend and I find I don't have matching DLC to play in his game. I deleted the Dog Outfit DLC from my hard-drive (because let's face it, it kinda blows) to see if it would make a difference. Now, I can't load up my game because I need the DLC to access the saved file which seems really unfair having pumped 25 hours or so into it so far and I feel I'm being condemned into playing with people who've been stupid enough to also buy the doggie DLC. Is this a widespread issue? It needs to be patched asap.
