Odd, can you tell me more info about the issue? Like, what device do you have, and where did you save, does it happen on the free / full version or just one of them
In what country was that device sold to you? It might be an issue with the local environment of the device (Unlikely though...)
Do you load a save from the main menu ? Or from in game? (Or both)
Where did you save those save files in game?
Did you wait a little bit? (Might be just loading)
Do you have enough ram? (Might be too many open things at once)
I'm asking all of those questions, because I can't reproduce the issue myself...
