Yeah, I've occasionally found that I lose the last few minutes progress if the game crashes. It doesn't crash very often, though.

I haven't noticed any of the graphics issues you've mentioned though (and I'm still getting four crystals per region) but I generally find I have to load it twice before it comes up properly, and it always opens with a specific orientation (I have to flip my iPad around and back again if I want it to face the other way up). They do seem to have fixed the way it would often stall and wait for Game Centre, though.
