[0.16.51] Corrupt map, unknown tile 0

[coffeeIneed]

I was playing a game, manually saved the game, and it also generated the autosaves (3 of them), successfully. I logged out of Factorio, out of Steam. Upon trying to load the game again the following day, when clicking on "Load", I get an error that reads as follows: "Corrupt map: unknown tile 0".

-This is a vanilla game, I've never had mods installed on any Factorio games.
-Ran a disc check for my computer, disc is fine
-New games save and work fine
-Both my HDD and SSD drives have over 100 GB of free space, and I'm running with 32 GB of RAM, on an i7 gaming laptop
-Verified game files as well

Here is the game save:

Ive also attached the log showing me loading that game save.

The game save is entitled "Ishwill kitty cat"

Would love to see if this could get repaired. Thank you to anyone who is able to help.

Thanks for the report however without a way to reproduce it getting into that state there's nothing we can do.
