Hey so I'm hosting an MSO server for a small group of friends and when they die most of the time their game crashes with "ArmA2OA.exe stopped working" It doesn't happen to me even though it's running on a dedicated server, does anyone know what this might be? It doesn't happen on any other mission. I'm also having issues with PersisentDB, getting stuck on "Client is loading persistent player data", I can move and shoot but it's stuck on the screen. This only seems to happen when I'm running @ArmA2NET, when I'm not I can play the mission but it doesn't save when I restart the server. Any help is greatly appreciated.

Made pancakes.
