Oh, good thing I had only just started playing the game. Thanks for fixing the problem so quickly!
By the way, after winning the first battle on Hard easily, I got bold and set it to the highest difficulty. I should have remembered from Luxaren Allure's final boss that you don't mess around in your games, because I promptly almost got obliterated by the very first boss right away.
(Do defeated party members still gain EXP, by the way? It seemed like that to me, at least.)
