Ok so I am gameplayer113(the one that started this conversation for the problem,and i forgot password for the account so im using this one now) and i think that i have found what causes the lag and game crash so today i installed app again from appstore and didn't connect to my gamecenter (with lvl and stuff that i had) and the game had no problems so after that i reinstalled the hacked ipa and again didn't connect to gamecenter and the game had no problem. So in conclusion for this problem i think that the shop inbox crashed the game and caused a lot of lag because i had like 1286 items there and also i had a lot of money i mean there is no other thing that could have caused the problem i didn't craft nothing unreleased (i was only on level 36 so i only had the things released to the game available for craft),i wont use the old gamecenter account because it's so hard to remove 1280 items without jailbreak however if u are jailbreaked try to use gamegem or igameguardian to remove the stuff u have and hopefuly it fixes ur problem.Thanks for the support to all that replied.
