Yesterday my computer crashed and even though RimWorld was turned off, the save file got somehow corrupted. The game was made in A16 release.

The output log:

The save file:

The file is literally just zeroes. 13.5MB of zeroes (in hex).
Something went really wrong with your HD or PC, but I don't think this is a RW problem. It occurred when RW wasn't even running.
