It's a bug that has been already reported. But devs are currently focusing on Ragnarok. Once they finish Ragnarok they will come back and finish Valhalla but at this point I suggest you to read the change.

Ok thanks for your reply. I did notice just now that if you sprint all the way thru the entrance and don't stop till ur in the bigger area, you can get in without teleporting :)
