LIL_NUGGETS'S PROFILE

Alright so i've got my fighting system going on, and there's a specific skill that lets you switch to another class mid battle. Making the transformation was simple and it switches you back after a set amount of turns, but my real problem is when the battle ends. Now if I win the battle with the character using this secondary class, he obviously will stay that way afterwards, which I can easily switch back on the map screen, but the experience points will go to the second class, and when I switch back, its as if the fight never happened when it comes to gaining exp. This really sucks because there are several different skills that let you change into seperate classes, and this just ruins it. Maybe there's a simple way to fix it and im just stupid, maybe its not possible and i have to do it another way, but i'd appreciate some help, thank you
