I'm sure this has been posted before, but hopefully the Devs are aware of this issue. When you join a game the game will be full, but will be in a never ending loop of trying to retrieve the session details. Lots of times I'll end up quiting the lobby only to be put right back in the same lobby when searching for a new game. This definitely needs to be fixed, and I'm not sure what causes it, but quite annoying.

Same here, seeing this too much lately:
For Crytek-what does "retrieving session details" mean when the lobby is full waiting to start the match?

Plus why does it boot half you party out to the lobby because it puts you in one of these (retrieving cycles)?
