Just to put this out front, I deeply deeply appreciate what you guys have done with these debs. Going to my problem and others have noted, I have closed the game if the environment does damage and reduces my hp to 0 many times. This is closing the game before the game could say 'game over' and I would close the app from multitask and go back to settings to make sure they're all toggled on, then load the app again to resume battle. My hp is full again and the environment would re-attack my full hp down to 0 and I would close the app immediately back to square 1.
From this point on, I'm forced to redo the scenario or just use a gem. Most of the time I quit and accept the loss of stamina, but if its an event boss (Enel), I just use the gem to recover and finish it. But for other maps from the storyline like Crocodile, I actually have to uninstall the deb to finish the map and reinstall it after since any damage dealt to me would crash the game and I cannot resume the battle.
I apologize for the semi-lengthy post, but I extremely appreciate the work you have done with this deb, but the somewhat small problems are something I have to go around with and I hope this post will shed some light at least.
