Asking Merxia Vendicci (TR_m3_Merxia Vendicci) about promotion gives an inappropriate result if the player has reached Factor rank. A unique greeting is required for this case. Moreover, a limit should probably be implemented for how high she can promote you, in order not to risk interfering with the Bloodmoon colony questline.
The topic Rumus Stannicus should have NoLore filters (or I guess T_Local_NoLore).
The door markers linking from the interiors to the two exterior cells that were transferred from TR_Mainland to the Roryn's Bluff section for working on the dried riverbed ((0, -20) and (0, -21)), seem to have disappeared. Thus, one cannot exit these interiors without using the console. As far as I can tell, the affected interiors are Verano Farmhouse (two doors) and Malumed (one door).
An interior load-door in the Andothren Port Authority is inaccessible, as an in_hlaalu_corner piece is blocking the doorjam.
This can be seen by going through the southern exterior entrance that's raised up on the stairs. There are screenshots below.
This was noted on the Discord server back in December -- it doesn't look like it has been fixed yet, and I can't see anything on the bug tracker about this issue, so I'm adding it to the bug tracker so it isn't lost or forgotten.
Between Helnim and Marog, there is a quest to help Tabus Norin and Merias Tolode (Avenge the Knights). It involves escorting these two and going to the nearby cave Galseah, to rid it of the Daedra worshippers. The issue is with the stairs and terrain in Galseah, Deep Caverns.
I found doing this while escorting them, to me - impossible. In the Deep Caverns portion, there are a few places where they inevitably seem to get stuck.
OpenMW possibly makes Viccia Hitaria not float properly for the MG quest, but instead makes her hover slightly over the ground. In Viccia Hitaria's Home in Bal Oyra, MG quest "Head in the Clouds".
