I think there is a bug in the new defense program.
Here are my starting Strength/Defense (S/D) values: Strength = 1947, Defense = 1625. I go to attack Phantasm Boss. I click on Train Strength which does the first attack. My S/D values are still good. When I click on "attack again" my S/D values go down to Strength = 1108 and Defense = 770.
what's up?? I tried a few different bosses and the same thing happens. Once I get out of attacking a boss, my S/D numbers go back up to where they are.
