Actual game crashing/freeze

I have had it happen only a couple of times.
The freeze crashes I had seemed to be map issues ... going to the same map spot would crash it reliably.
Crash crash out of nowhere once...

These issues I noticed over a year ago. In the last year and the lions share of my 2000hrs/30 some worlds have been crash free.

I do not mod my game.
Win10
GTX 1070
16gig ram
I 5

I may have lost a couple of hours in those crashes, but overall meaningless issue and I didn't know about the .old files you could rename.<or whatever the backups are called>

If your machine has any weak points the game may make those obvious.
