[0.16.X] Corrupted map, contains id not in the dictionary

[Spook]

After I came back from vacation I wanted to continue to play my map, but it suddenly won't load anymore and gives me this error: Corrupted map, contains id not in the dictionary: 51456

Several of other saves have the same error.

I use NO mods, and I'm using the newest 0.16 experimental version. I think I played this map last time with .28
I tried to load with the newest .32, with .28 and with .22 (It gets shown as used base Version somehow?). But non of these works.
The autosaves are overrides by other bases unfortunately.

Can you please help me and fix my save? I'm doing a Lazy Bastards Run with a special Grid Layout and I advanced to blue science already. I would like to finish this run. (if you are curious this one: https://www.reddit.com/r/factorio/comme ... grid_base/)

I attached my save file if needed. Please help me.
Thank you!
