Multiplayer seems to be broken again, from 8 games my team mates got disconnected 5 times, i see a lot of users getting disconnected at the start.
One game, so not enough to confirm a pattern, but the disconnecting player (= no check mark during load screen) had an Xbox icon to his name, while me and the others had a www icon and a check mark. The game was just stuck in loading screen then eventually crashed. 1v1 seems to be ok.
