Yes we play for hours and then we all save our playerdata, and then when everyone is gone i press "server save and exit" and wait untill its done. But then when we load the mission we get that error spammed when the first player is starting the mission. I get stuck loading but hear ingame sounds like the waves, after alt-tabbing 1000 times i get rid of the loading screen. But our ALiVE markers are gone and we have errors in the log. objects are pretty much where they were when we exited, sometimes sandbags and such are in the wrong spot, and some vehicles have appeared in our base. But our biggest issue is the ALiVE markers are gone, AND sometimes we cant place down new ones, and in the map view "ALiVE" is missiong from the top left.

hope that info helps painting a picture of our problem!
