[2.0.42] Crash loading all saves: "Corrupt map: unknown quality prototype ID 65"

[Padmasambhava]

Single player. No Mods, just almost 300 hours of factory building. Yesterday was a normal session in the evening, setting some quality recyclers. Today - all saves are dead due to the same error.

I followed this one:
viewtopic.php?t=101840
Did not help.

Log, manual save and latest autosave attached.

Would be great to fix this save, as I have no other saves of the last 100+ hours.

It would be nice if game kept an incremental save for example every X hours (configurable in options). As it seems that people are not making any manual saves, at least not regularly.

That's an extended autosave. Fills smaller laptop disks easily with bigger maps, difficult to manage for the players.
It's also difficult to make players do backups and copies. If they realize they need them, it's too late.

I make a new save every day I run the game, then save into that file this day. 1st day is 000, second day is 001, and so on. My current save is 056.

Additionally, I increased the amount of different autosaves to 10. Everything is synced with Steam, and I run daily local backups of my machine. I never had a crash, never had a corrupt map in my 4 years of Factorio, but if there was one, I have plenty of previous and not too old saves to go back to.

I have a strong feeling that I have the same problem as here:

Is there a way to manually get rid of the laggy blueprint?

I do the same. Increased number of Autosaves, and also create manual save several times during gaming session. My save number is over 300.
I don't expect any corruption though, because I don't run Intel processor, but Ryzen with ECC RAM instead. Also Btrfs Raid1 as filesystem.

That looks like a classic bit-flip, even if it was inside of one of blueprints. Since locating the issue was relatively fast and it was possible to fix with hex editor, here is a fixed save:

Good news: all fixed! Thank you very much for your fast and helpful reply!
Bad news: my wife will be unhappy about it.
