Hello, at daytime i am playing on PC but at night i want to play on my phone. The next morning i want to switch the save back. Is there savegame-compability between those versions?
You can take a 1.4.5 save and load it into 1.5.2 and you'll be fine. As soon as you save, though, it'll be a 1.5.2 save and no, you won't be able to play a 1.5.2 save in a 1.4.5 game.
