Amazing gameplay lots of crashes

Love this game its actually probably my favorite! I have a mini iPad 2 and it cant run much but it can usually handle this one and its a simple concept executed perfectly incredibly rewarding (minus the cringe of not getting a four star hero at the tavern) I was getting really into it however and then it crashes for two days now whenever I try to do anything besides look at the map it crashes although they do reward the players with a generous pile of gems if it crashes enough times but please fix! I want to play again!

Greatest ever!!!!!!! about Mini Warriors™
