I rolled an alt recently, and got to chance to go back to one of my favorite zones in the game; Khenarthi's Roost. I had a lot of fun, but I found a few bugs. Some old, some new, and one or two that were pretty funny.
A storm cloud indoors. I'm not quite sure if this is an actual bug, as the tower has no roof, but it really doesn't fit. I remember coming through here before without seeing an indoor rain cloud.The skyshard tower in Eagle's Strand:

This guy looks like he's sprinting, but he runs slower than most NPCs walk. He continues on one circular path being followed by a goat at the same speed. I found that after leaving and returning he's actually walking and looks normal. Gogni the Redguard just south of Mistral on the mainland:

I can mount a horse in this ship in Mistral. That's cool.

But when I try on the deck, the game's all like, "Nah, man. now's not the time for that."

This time around I decided to let the green lady kill him. He stayed like this for about 3 minutes before I tried leaving the house and coming back. He was still like that. I had to turn the quest in to get this to stop. Ambassador Ulondil in Mistral:

I know there are some others, like not being able to access guild bank or guild store at the banker in Mistral. If you guys find anymore please add to the list, and upload a screenshot if possible. Hope you enjoyed!
