No mods, vanilla game. Everything seemed fine, saved the game, no issues. Then went on to do something in my test map (overwriting all my autosaves in the process) and when I tried to reload my main map, I get "Corrupt map: unknown tile 0"

You should definitely post your corrupted save here, otherwise the devs can't help you.

Apparently the attachment didn't work, so here is a link to the file: https://www.dropbox.com/s/z7ncjxm26oc5v ... e.zip?dl=0

Btw. it would be great if the forum would show a bigger warning when the attachment fails, and not just the tiny exclamation sign.

Sounds similar to my report. viewtopic.php?f=7&t=69694

Does this still happen in the latest 0.17? I believe it was fixed.

I still can't open that save file. It was the only time when a save was corrupted though, so no idea if the bug that caused the file to be broken was fixed.

I was thinking this was the entity ghost circuit connector corruption but it's actually a different problem. Your save file was corrupt via some external error. When I go to extract the zip it gives a data error trying to read level.dat. There's nothing I can do about that, sorry.
