Thank you. After removing the APERS mines I placed (I could simply remove them in the 2d editor) it started correctly. Problem is fixed. However, each time I reload the mission some objects (offroad, quad, small camping table, spotting scope,...) move like 10cm while the rest doesn't so this leads to items bit by bit shifting to locations they should not be in and messing up everything (destroying camo nets, stuff that was on the table is now floating,...)

Is this because I placed the items on a small slope and is there a fix for this?

Thanks

2600K, I just replaced it with that and it loaded the mission without errors but as soon as I clicked preview arma crashed again.

It was at the bottom left and I removed it and then saved so it's gone in the mission.SQM but when I preview now it still crashes:

I do not know how I produced the issue. I didn't place anything special so I wouldn't know.
