Hey Coffee Stain,
Since the cloud saving update, I have been relying on it to save my factories and every time I'm prompted on loading I choose to use the "download from the cloud" option. Seems to have been working fine up until now.
Today when I started playing I realised that the save process screwed up somehow because I've lost a day or so of progress. The factory I've built is still there, but the work I did in the last day has reverted to what was there before.
The timestamp and date on the file when it prompted me to download matched up to the time I last finished playing, so I assumed the data would be correct, but it's not. I'm not sure if it's a problem with communication with the server, that the server has an old save file whose date was changed to match my most recent session, or if it has something to do with the compression of saves, but I'm almost certain it's on the server end.
The problem is if every time I use cloud saves from here on out and I can't be certain that the next time I load up there's no chance I've wasted my time to get nothing done in the game, I'll probably step away from what is otherwise an awesome game. I hope this issue is resolved in short order because visible progress is a critical part to the gameplay loop and enjoyment in this game.
Thanks for your time.
