Game or loading screen locks up whilst playing/waiting to join multiplayer wasteland games. No pattern, if I'm in the game it'll lock up at any point. Symptoms are screen locks up and holds last presented image (game or loading screen). Ctrl-Alt-Delete, start task manager and then I see an Arma 3 has stopped responding message waiting for me.
Game was initially fine, stability has got worse over the last few days. No sign of the issue during single player, although once the showcase missions were completed I've not gone back (loving multiplayer too much). Have tried the team v team deathmatch multiplayer once very early on, no crashes occurred but then found wasteland and have not looked back.
