Krishasch the Kobold getting stuck on Stairs

When being escorted up to meet the Kobold King at the end of the courage quest line,

Krishash the Kobold got stuck on the stairs.



I moved away far enough so he would say "Ok I go back" then he got the landing and got stuck there and would not proceed back to his orginal spot.



I was unable to talk to him during this time when he would not move from the landing. (picture where he is targeted, highlighted blue)

I had to exit the game and start on world map, and go back in. The second time around he got stuck in a door way on the next floor for 2 seconds as well, but managed to continue through it.
