Well, that sounds like a bug... If you can share your save file so I can try to fix it, but yes. A clean re-start may avoid it. If I'm right, I fixed a bug like that for 2.3.5 but I'm not sure if that's your problem.
If that's the case i'm fine waiting for 2.3.5 to be released here, tried a reinstall but the icon still doesn't appear though it could be because i can't actually delete the game off of android less i lose all my saves. How do you share a save file here from android?
