Too much XP gained after the Showdown?

Doing some battles, not even big ones and getting close to 18.000 XP every time?
Even some minor fights with some Hunters and Runners in the new mission can give over 15k XP.

Went up a couple of levels last night just doing a couple of the daily missions, roaming around little and what I belive is about half of the new story.

Its bugged. The XP meter does not reset so you are seeing how much you have earned in that session.

Had 2 seesions yesterday, the longer for more then 5 hours and during that I could see like 17.358 XP gained and then 8.414 XP followed by another 18.921 XP and a 2.337 XP. So it can’t be a “not reset” thing?

I have had this as well, me and my friend. Got like 25000 one time.
