Not sure what triggers this but the app force closes a lot. I am using the mod because I want to clear Phantom Trial but I am stuck on floor 45. (I switched over to the mod from floor 30s so I'm not sure if there are other lower floors the mod gets stuck on). The floor 45 boss attacks a couple times and when my character attacks, the app closes. This also happens in Defend! Heath -Wizard King (app close when character attacks).
Also lost a few times in arena (without cheat on) due to app force close - just trying to do my dailies.
