Version isn't experimental one, but factorio save failed 2 times in a week.
First crash was manual save ( no log ) , second crash was autosave ( save and log are attached ).
Autosave cycle is 1 hour (sure, usually successs ).
I run factorio 24 hours, and in same PC, I sometimes play other games, satisfactory ,etc ...

failed save :

That is likely a hardware issue, can you provide steps to reproduce the crash?

I think reproducibility is low, but it may happen when PC works hard.
I does 24h factorio 0.17.79 bob's play for several months, but these crashes happen really recently.

What information you want?
Memory: factorio 5GB, satisfactory ~5GB, PC has 32GB memory.
CPU: factorio 1 logical processor full 9%, satisfactory ~15%, PC has 16 logical processors.
GPU: factoro ~5%, satisfactory 50%

Restart from _autosave2 and run about 1 hour, I tried to do manual save then third crash happens just now.
PC works not so hard now, almost factorio only.

Last night, I reboot PC then re restart from _autosave2, several autosaves does well.
I usually reboot PC about 24:00~26:00(JST) on weekdays, but sometimes forget to reboot on weekends. ( Monday morning now )

Hello, I agree with Loewchen's assessment that there is unfortunatelly something wrong with your PC and the crashes you are experiencing are not caused by a bug in the game.

Given nature of the crashes and that it got worse as the map got larger (that's my assumption based on what you said), I'd suggest you to run memtest overnight on the computer to check the RAM sticks.

BTW. I let your save run on my work computer overnight for 12 autosaves with 1 hour autosave intervals and it didn't crash.

I am now running memtest86, thousands errors appears.
(I built this PC in February, and I think no errors were there when built.)
Something are wrong, memory or cpu or motherborard,...
I am finding out more and to be repaired.
Thank you.

I found 1 of 2 memory modules has errors.
Sorry for the inconvenience.

There were no trouble except factorio (save) , but maybe I just didn't notice that.
