Storm dragon low xp

I believe this has been reported before...after I killed a dragon in a quest, it only netted me 26 xp. 18 without bonuses. That seems awfully low.

It only had 400 hit points though, so I guess the whole encounter is a leftover from a previous version?

Edit: I am trying to upload a screenshot, but so far no luck. If someone can tell me how to post a pic instead of a link, I would be grateful.
