[2.0.66] Crash and save corruption "HeatBufferPrototype: long-handed-inserter got bad index"

[koyuze]

Playing space age with no mods (besides quality and elevated rails)

The initial crash left me with this message

12352.696 Error HeatBufferPrototype.cpp:172: long-handed-inserter at {185.500, -18.500} got bad index: 761970
12352.696 Error CrashHandler.cpp:643: Received 22

after restarting the game I found that all my auto saves were corrupted as well as my main save.
the message said
52.999 Warning Map.cpp:364: Map loading failed: Corrupt map: unknown quality prototype ID 255. File has likely been corrupted due to failing hardware.
53.228 Error AppManagerStates.cpp Corrupt map: unknown quality prototype ID 255. File has likely been corrupted due to failing hardware.

and trying the other save files this message came up
63.919 Warning Map.cpp:364: Map loading failed: Invalid bool loaded from input file. File has likely been corrupted due to failing hardware.
64.171 Error AppManagerStates.cpp Invalid bool loaded from input file. File has likely been corrupted due to failing hardware.

I ran a diagnostic on my computers memory but the system found no issues with my ram.
computer specs:
Windows 10
intel i7-7700
GeForce RTX 2060 12gb
Samsung SSD 870 EVO 2TB
Corsair Vengeance RGB Pro DDR4 3600 16gb (have 4 of these)

Not sure how to repeat crash or corruption. I would like help in identifying if the issue is with my hardware or drivers because I don't want to lose saves to this problem again.

Save corruption like this has virtually always been traced to bad hardware: most commonly failing RAM but also sometimes failing CPUs.

Factorio is not tolerant of failing hardware because it expects things to be correct and failing hardware scrambles things.

I suggest running a memory test, but letting it run longer. And if you’re overclocking your RAM (XMP or equivalent) try disabling that.
