[1.1.21] Corrupted Map

[Nawlidge]

After updating to 1.1.21 my map has been corrupted! I was playing normally, saved my game, relaunched it and now it gives me the following error: Corrupt map: unknown tile 0.

I was just building my first rocket, so any help would be appreciated!
Not using any mods, complete vanilla.

Find attached my Map file and my log file!

Hello.

I have exactly the same problem.
After updating, I saved my game progress. The game save will not load.

Error message: Corrupt map: unknown tile 0

Version: 1.1.25 (build 58135)

I lost a lot of playing time. Please help me.
