Yesterday I was playing campaign & the person I was playing with left.
I backed out to lobby & played the last 3 missions by myself (I died so much XD) The game still seems to think I was playing with someone though, as at the end I got the Bromageddon achievement. And if I look at the stats it sais he was in the game. He wasnt
Any clues?
Something similar also happens in MM. If Im in a party of 4, & 3 people exit, leaving only me. The game still assumes I have a full team & will match me up with another full team showing the people that left as crosses in the leader board.
