[0.17.79] Error: "Map loading failed: Invalid index 216 for Direction"

Hi,
I recently suffered an untimely death at the hands of a giant worm on my Seablock map. I attempted to load the last autosave, to which the game crashed.
Relaunched the game and all Autosaves and the main save "New Seablock", all generate the same error.

I can still start a new game, just not load a seablock save.

Any suggestions or more information required, please let me know.
I was not able to upload my 350MB Mods folder, please let me know if needed and how I can do so.

Thanks for the report. Can you try running memtest86+ https://www.memtest.org/ while I look into the save? There's always the chance with these corrupt maps that it's just bad RAM on your end and that normally quickly points it out if that's what it is.
