Been getting class change penalties in a leve without changing classes :(

Didnt read the thread in full yet, but yes.
Doing Lv30 leves as a Lv40, no matter how many stars you make it, will lower your exp reward. (As stupid as it is, raising the stars should give MORE not less.)

It does gives more if you raised your stars, it only gives less because you are no longer on optimal level.
