I’m sure everyone else is having the same issue; you can get through the first Boss (Spark Kill), but the second Boss Fight (large room with Loot Chest after Rally Flag)) fails to open an Exit Portal to resume the next level once you’ve completed killing the Boss. I’ve been through it with multiple different Teams; same result. Doesn’t matter how long you wait or do. Team Suicides just end the match. Personally, I really miss the 50 level Onslaughts, but for now it’d really be great if THIS PROBLEM WAS FIXED.
