I am trying to move a Colony from my laptop to a Chrome book so I can have them both working at the same time. Normally, I would export the .mcz file move it to my Google Drive/OneDrive shared storage and then import it to the new PC.

The process now fails and gives the error 'Save file corrupt'. My fault, but I lost close to 3 days play and gobs of resources creating a storage map. I deleted the game from the original laptop before importing to the new Chromebook. (650 quantum warehouses, *POOF*)

What is the new process to move a game file?
