Thank you very much. You just saved about ~300 hours of gameplay

I've been running Factorio for some time and I decided to restart the game. After trying to load the save I get an odd error Corrupt map: unknown tile 134. I get the same error when trying to load any of my 1.1.33 saves. However I can load very old saves from 1.1.32 without any issues. I'm not sure ...
