Re: Strange thing with sync and cloud
Keep is separate from cloud saves. Cloud saves are for pretty much all origin games, and has been both a help and hurt at various times for different people. Generally speaking, if you only use one PC to play games on, then most times it will not help you. The exception to that would be if you buy a new computer and have cloud enabled, it would then simply download the saves back to your new PC when you started playing, by asking if you wanted to sync and did you want to use the cloud saves instead of what was on PC.
The issue always comes if you decide to use the cloud saves, and there are less or they are corrupted, then they replace all your saves on your PC. That is how you transfer between PCs to keep playing your game, by it downloading and overwriting your current PC saves to the one you uploaded with a different computer.
