It's was on but we switched it off again as the save games are currently too large and causing problems on the Cloud. We'll make them smaller and reactivate the Steam Cloud soon. In case anybody wonders, all save games (big ones and small ones) will remain compatible with future updates.
Do you guys have any idea on a time frame for this? Is it something you expect to have this done very soon? I have two different places I game, and having cloud compatibility would be a big help, so I'm just interested to know when I should expect this, even if it's a very rough estimate. Thanks.
