I have this problem frequently, since Beta 5.1 I think?
only see the out of memory crashes on 32-bit version. Win 10, gtx 1080 gpu, amd fx9370 cpu.
I've found it can happen on any map, but biggest culprits are Outposts & Sunrise. But ive had it happen sometimes on Tomb, Field, Field X & Walls
Would sending logs help?
64-bit version gives me its own problems. Game hangs 95% of the time when I access the PT menu.
