Something is wrong with this game for me :(

Keeps kicking me out of the app.. Freezes.. I reached mission 17 and it kicked me off. Turned off my phone and back. Wouldnt load.. Had to delete the app to reinstall.. Lost my data... Fun game but something is wrong with it on my iPhone 6+, all that hard work!

Nhista about Royal Revolt!, v1.6.0
