-about lucky patcher i use the module xposed framework (way working without) if your bluestack is rooted
-for copy paste lib on /data/app you need to allow write permission on root explorer
-apparently this game use a sort of backupfiles stored somewhere
-i test my mod on new profile account and following game tutorial correctly its maybe this why it working for me.., if you dont care of your progress you can try to change device id(on bluestack in your case) using titanium backup pro.
sorry if i cant help more.
