Hey guys! Short post here but I just wanted to let everyone know we discovered a bug in the Spectator Mode yesterday that was very likely causing most of the crashes. We applied a potential fix last night and we didn't crash once in the last 24 hours, so we pushed our luck today and tested 3 COMPLETELY FULL 64 player Inferno Cows, and we cleared all 3 without a single hiccup. Spectator Mode is now also more reliable as well, so I can finally proudly say Annihilus's main feature is now back and here to stay! Enjoy guys!
If you try to join a game with more than 8 players and seem to crash, just create your own private game once and it'll fix it, although this seems to only affect very few people and after joining your own game it fixes it for good. Have fun guys, and good luck!
