Some friends and I were messing around with the new toys in the game. I was lazy and didn't put any respond scripts in the mission so we had to restart every time someone died or a jet broke. Every time I restarted the mission the game would crash/ freeze on the briefing screen. I tried it on both Altis and Stratis. Altis wouldn't load launch at all and Stratis had the bug. The crash would happen to everyone in the server, we got wise and backed everyone out before the server was restart so only the host had to relaunch.
