I've just cleared the Nashkel mines and defeated Mulahey and his minions. After retrieving Xans blade from the chest and looting the area, I attempt to exit through the door I came in and the app crashes to home screen. When I load my game back up, both my quicksave (taken immediately after killing Mulahey) and auto save are corrupted - they both actually load up a game session of my previous quick save. The preview for my quicksave is a grey box, the preview for the auto save is my party grouped up by the exit, even though both these saves take me to a session before the fight.
I have to say, all these crashes are getting very annoying. They mostly seemed centred around the save/load screens for me too. You have to constantly quicksave in case of app crash (losing progress) but then loading seems to kill the save files quite often for me.
