A bugfix version has been released on the market : 1.2.2
It tries to fix the problem some users are experiencing while waking up from sleep.
Sometimes, the game just throw an “array out of bound exception” and crashes … It seems to be due to the skin system going offset for unknown reasons. The current fix is just forcing the skin to default one if any error appears.
I hope people experiencing crashes will be able to play the game 
Have fun !
