The dialogue for the "Vintage goya" topic (present in the Ando HH questline) is wrong. It says that it's a fine Cyrodiilic liquor. It's actually a fine hlaalu-made liquor (a native counterpart to flin/cyrodiilic brandy).
If the player enters the locked room on the 1st floor of Aurelia Draconis' House in OE, the game improperly starts the FG quest "More Rats?" at stage 30.
The Helnim Guild of Mages NPCs have this line in the "someone in particular" topic: "Areanne Vara is the Guildmaster. Her residence us at the top of the tower. Besides her, all the important people in Mages Guild's Telvannis branch are in Firewatch.". This line is correctly filtered to exclude Areanne Vara.
You can ask Amelphia Tarramon about various kinds of Morrowind liquor (sujamma, greef, etc) before beginning the relevant quest (Mages Guild: Four Types of Liquor).
The NPCs in Dilitan Mine, which is controlled by Telvanni (specifically Master Vaerin of Alt Bosara), are assigned to the Indoril faction, including the slaves (who shouldn't be in any faction).
