Great game just crashes

I love this game I play it as much as I can. I recharged on gold and got the kamui rikkari move for kakashi. Every time the fight goes long enough for him to use it. The game crashes every single time. Im giving a three start for now until I get to actually see kakashi use his new justu. Also can you possibly make the event last just a few day longer atleast. I was very upset when the minato namikaze event came out. I had to get just six more chakra and the event ended. So to prevent that happening to me and others. Can you please fulfill that request. Thanks
