When I log out and anything I was working gone doesn't save when I login in I see that My progress doesn't save.
hmm... did you log out w/ or w/out wifi? if so the games wouldn't be able to back up onto the cloud
I sign out with wifi but it might be a problem with not saving or something like publish it than once you login back in unpublish it.
Did you upload your drafts before you logged out? You have to do this or else all your recent progress will be lost.
Not really but this has happened to me before but I just redo it unless its not important but i'm working on this game and I was making a pixel character than I logged out to check something on something else and. I wouldn't want to restart but at least it doesn't have lots of stuff for the character.
