Oh actually my girlfriend said she installed an update the other day and it hasn't crashed since then so hopefully that's sorted it.
I'm a bit weird and have to get everything on each level before I move on so I haven't finished the game yet, some of the levels took me a good while to complete. I've been spending quite a bit of time on the challenge modes too, some of them are really hard to get the gold on; I can this this game taking quite a long time to fully complete.
Feel free to add me btw, my username is Coleman316. I don't have any friends yet
