Core/Player: Dungeon Finder quests don't follow the same rule as repeata...

...ble quests, they should award experience every time they're rewarded

Differently than repeatable quests that award experience on the first turn in only, Dungeon Finder quests should always award experience.

Currently experience is being awarded only once per bracket, i.e once at 10-20, then 20-30, etc as experience isn't given after the first time they're completed.
