Seems to be a PC issue as I didn’t encounter this bug when I ran RoM on console so I can speculate it is a platform specific bug. Dually note that if it happens on console post-FoA (flames of ambition.) Then it proves each update breaks something in older content.
If you see me anywhere. Know that I am sitting back with a bag of popcorn, watching as ESO burns the goodwill of its player base with practices that only disrespects the players time like it did to me and many others...
If a game does not respect your time, best thing to do is move on from it and find something else.
