During closed Beta i had 100 AP from another game left over, now they gave us free ap for the closed beta event, now i have 20 ap, i was wondering what happend to my ap that i had and if i can get my 80 ap back?

from what i understand they gave all closed beta people AP for grand fantasia and it showed in game and was added to the AP you already had, if you used over the amount they gave you it would be taken out of your normal AP
this is most likely the case for you, so the AP is not missing you just spent it as you spent the free AP plus some of your own. i am fairly sure i did the same thing
sorry if you where confused by this

hope i have been of help =D
