Hi
Been getting this over the last couple of days. Not only affecting me, but everyone else in the game as it’s the same people over and over again, all talk about it in match chat.
During a game (had it in both quick play and arcade), screen goes black then “The server closed due to an unexpected error”, kicks us back to character selection, we go again, same error, kicks us all back to character selection rinse repeat.
It’s only resolved when leaving the game (which incidentally dropped me from a level 4 endorsement level to a level 3 which I am a bit peeved about)
