[2.0.20] Invalid heat buffer index

[Lukedude2244]

Was just playing and when it went to autosave i got a notice saying "Cannot save map: Corrupt map/memory corruption: invalid heat buffer index: 2147483930 >= 384" is there any solution to fixing this since its preventing me from saving.

It most likely means your game was corrupted in RAM while playing - there's nothing to do but roll back to the last save that works.

You may also want to check your hardware for faults, but sometimes bit flips happen randomly.
