This is going to be a tough one. We need to identify what series of actions results in the file being erased and an empty file being put in its place, but if it's not easy to reproduce it, that's going to make it difficult. Let me ask this - can we remove Google Drive sync from the picture for a little bit to see if the issue occurs without that? We just need to identify whether that has any impact at all. If the problem happens even without Google Drive Sync in the loop, then I can focus my testing on just MobileSheets itself in a controlled environment.

I'll review the code, but I would imagine the only thing that might cause an empty file to be generated is if MobileSheets tries to write to the file but that fails for some reason.
