Emercius Ludoviil of Old Ebonheart in his 'background' topic mentions all the little flags hanging above the alley and how that is one of the ways the local Union of Guildless Traders and Craftsmen is trying to improve commerce. Except that there are no longer any of the flags left (sadly), since OE was trimmed down for performance.
Marayn Voldal of the Howling Hound in Vhul has a generic 'food' dialogue option (likely for all publicians) that lists what beverages the pub has to sell. Unfortunately, this list does not match the barter inventory.
"I've got the good stuff, too, behind the counter -- Cyrodiilic brandy and flin -- but it ain't cheap." - except he doesn't sell either. He lists all of greef shein mazte and sujamma but I don't believe he sells all four either.
In vanilla faction quests, questgivers never tell you "This was your last job. You've accomplished everything here. You should look for jobs elsewhere." immediately upon finishing their final quests. It sounds a bit too gamey compared to mundane jobs, and more importantly, it deprives you of directions to other faction cells because the player has no reason to click on jobs/orders/duties/etc topic after reading that.
Issues related to NPCs not attacking the player during the Orlukh questline:
If the player attacks the Hlaalu caravan guard first in Roadside Picnic, then the other caravaner won't be hostile until she is attacked herself.
The spa guard at the Andas estate attacks a vampire player on greeting them, but then immediately returns to being passive on successfully hitting the player.
Given the level of control that the mabrigashes have over the other NPCs at the stronghold, it seems strange that everyone other than the sisters attacks a player with vampirism, including the slaves in the propylon chamber with the elder sister. The younger sisters in the dome even have dialogue reflecting their relative lack of hostilities towards a vampire player.
