I have experienced all of these multiple times. So they are repeatable, and I am sure that I could document these better if I wanted to. Char On Fire - When the tank lights me on fire my character animation doesn't change back. I feel it has something to do with some of the abilities (happens often on the assassin and sometimes on other chars) but if i catch on fire and get away my character will still be on fire until I die. It is noticeable by other players in the game too... resulting in not being able to cloak as the Assassin anymore. It is annoying but harmless to everyone but the Assassin (kind of cool for other classes). When it first happened I thought it was a feature like NBA Jam! 3 Kills and you're on fire! Ability no longer recharges - When I spawn I have had my ability just not charging up. It is unusable and you have to die to reset it. Game Freeze - When a game ends or starts (can't remember which) and the host quits it kicks me out to a screen with a floating MNC logo. It requires me to quit to the XBOX dashboard.
First and last are definitely known issues in the bug list. The middle may be, too. I wasn't going to repeat the first response to that end, but the NBA Jam bit would be awesome. "He's heating up!" "He's on FIRE!" Also, we need Cantor to say "Boomshakalaka!"
Ahh now I see them... although the 3rd issue is just labeled Host Migration Issues Ahahahaha... yes that would be on my wish list! More funny commentary!
