So Ive been having this problem when trying to date dungeon with gf. i get the exp but she does not get anything from it except for like 180 exp per monster while I get minimum of 3k then 900k at the boss... Did it three times with this happenening and I would like to help her level.. Any help to this would be great! Edit: also forgot to mention when we are done with dd we cant exit until it tells us we failed it agter killing boss..
