Once a crash - once not

[Cynomys]

I don't know what's the reason for, but today I had an oddly problem. During the game it crashed to desktop. I started again, and loaded the last autosave. The game crashed while loading. Same with 2 other, older autosaves.
I tried to start a complete new game. Ctd. Then I thought for deleting the saves, but anyway I clicked on the last save I made. Not an autosave. And this one worked. I played several rounds, saved again. Then I tried again to start a new game, and this worked too.
Has anyone an idea what happened there? Can I do something to prevent a crash in future?

I also have CTD on loading some saves direct after a new start of AND but loading the very same save from within a game (like a older working save game) then worked perfectly.
