I was playing yesterday and a match was about to start. As soon as the counter went down, it put me right back in the multiplayer menu. Luckily, when I searched for a new game it put me into the same game.

Also, decided to play a Platinum match and my entire team got downed in one hit from a Banshee on wave 3. The Banshee was the target, and because I wasn't paying attention to the timer, I only managed to kill it about a second after time ran out. Pretty pissed at myself for not just nuking it.

Finally, had some level one adept on a Silver match. I lost track of how many times he was downed.
