“An error occurred during co-op play”

Does anybody know why this happens in firefight? I get the titular message during gameplay and am booted back to the lobby along with(presumably) everyone else that was in the game. This never used to happen when the game was new but as time goes on it gets more frequent.

They’re doing some maintenance so that could be why.

I get that they’re doing maintenance as I saw the 343 employee’s post yesterday…what I’m talking about is an ongoing problem that keeps getting worse with time. Between this and the various problems with multiplayer matchmaking searches it seems like 343 is trying to get us to play their newer far inferior titles. That being said…I have no clue as to what entity is responsible for server maintenance on Xbl…individual game studios or Microsoft as a whole
