Wow, 99 friends. I guess even in the world of video games I’m still not that cool. Oh well.
I didn´t know all of this errors that got fixed but I´m very happy about the DLC fix and the controller fix with 2 profiles. That was such a pain every time. I always had to go to the dash, log in the other person before we could play.
Thanks a lot 343i!
