When I meet Krishach and tell him I am ready for him to escort me he got hung up on the stairs. I left him and returned and hoped it would reset the escort but he just made it back to the bottom of the stairs and the escort was still taking place, even though he was unmoving. I logged out and back in again and I can talk to him now and ask for that escort again but after he says, "Get out of my way!" he doesn't move and just stands at the bottom of the stairs. And another thing, which isn't so much a bug as an annoyance, is that with these walking escorts like this one and the ones in Valhold etc., the avatar's walk speed isn't fast enough to keep up and the run speed is too fast. I have always thought the avatar's walk speed was too slow, which is why I never walk even though it would be nicer for going up stairs, esp. spiral ones. The av speed should be increased to at least the same speed as NPC's walk.
