Unable, crash seems random, in my case was triggered by an unseen grenade explosion.
RPT, BIDMP and MDMP file sent in a single WinRAR archive.
Can confirm. Just happened to me too.
I was playing with ACE but I don't think that's the problem in this case.
Just tried to load my mission on the Stratis via editor and arma 3 just crashed. On the next start of the game the same mission loaded just fine. Here's my crash log.
