Every time I play the game for an hour or more I get a bug where the game fails to auto save. The save icon just stays in the bottom right corner and never goes away. Since the game is stuck trying to save no further progress gets saved. The first time I probably lost about an hour of progress due to this bug.
This is the problem with only having auto saves and not letting us save manually. If something happens to the save we are screwed. My personal opinion is that all RPG:s should have manual saves but if that is not an option please make sure the auto saves work perfectly.
