This is a very niche issue but one I've had brought up in my guild a number of times: the Revelers NPCs that got shoved in for some holiday thing and are still lingering... they've ruined the ability to host public RP taverns in several places - in particular, the one I find hurts the most is The Ebony Flask in Stonefalls.
The Ebony Flask used to be the only practical Dunmer tavern in the mainland Morrowind zones - had plenty of room, had a proper bar, and a good location (easy access). But when it got crammed full of revelers - it makes the place too crowded and kills the RP immersion. It's been especially frustrating trying to pull together more Morrowind-based public RP but having no decent public place to hold it.
Anyone else not pleased with the "holiday" Reveler NPCs? I know they're other places too, like The Rosy Lion. Also, the fact they're wearing winter festival stuff year round is pretty obnoxious too.... lmao
