Hello,

thank you for the response. Could you please tell us if this happens when you try to save a mission in progress or trying to save a mission in editor?

However, we cannot determine what exactly caused your game to crash. It is necessary you try to run your Arma without any mods. If the crashes still happen then, please send another crashdumps.

If the crashes stop (on Arma without mods), please try to activate mods one by one until you find out which one causes the crashes.

Mods are not official content from Bohemia Interactive and it is very likely that the CTDs you are experiencing are caused by collisions between two or more mods.

Please let us know, thank you.

I downloaded back main build then again development and everything works fine now. I dont know what was that but now its working. Thanks for respond!
