Pathing Wolfmaster Finnur and multiple Frostpaws in Thurg Mines

[Thulghor]

[This is on Green Server if that matters] Not sure what is going on here, I'll try to take a video via OBS, but while camping Tar Goos for heads and watching anime in the Thurgadin Mines, I noticed that Wolfmaster Finnur and Frostpaw aggro...something in the mines, usually a rat or a bat, and charge on in there, either via floor or wall aggro. Then they path back, then run back in and so forth. However, after a while, I noticed it started spawning multiple Frostpaws. One seemed to path back and forth with Wolfmaster Finnur, the lone one just runs around in the mines, but sometimes glitches out in the entrance. Occasionally all three will jump a mob. I thought maybe someone was doing a quest, and maybe Frostpaw was related to it, but I've been the only one here for most of the day off and on.

So yeah, it's a little weird. I'll see if I can video record it.

I explored this some more, but it's pretty random so it's hard to time the video just right. I thought maybe the second dog was the dog Alpine, who seems to travel with Guard Halldor. They both end up down here as well, although it is more rare. But no, this last time it was two Frostpaws up, although one was super glitchy. (Would have added as an edit to the original post, but it's edit restricted.)
