The storage room behind the bar in the Inn Between is not locked. It is generously filled with loot, open and has no guard. Shouldn't it be at least 40pt. locked?
For a large number of shirts, only the SD (256) textures exist in version 8 of Tamriel_Data, which does not look very good in a HD settings. Notably, the very same textures exist as HD (1024) versions in version 7. Apart from the resolution, I see no visible difference between the two versions, although I guess there might be some subtle changes. My conclusion is that the one who made those changes to the SD versions forgot to provide high-res textures.
If asking the scout in Cirifae's Tradehouse in Teyn about the local area, she will attempt to give the player an item that doesn't exist, which triggers a crash, so this needs to be fixed during the dialogue overhaul at the latest. There is also a typo in the entry, Fort Ancylis is east of Teyn, not west of it.
The sea floor between Roryn's Bluff section and Vanilla Morrowind is not bordermatched for the patch east of Fort Ancylis. The section needs to be expanded eastwards to account for this. Perhaps something to handle in connection with patching up claim #11 in the Roryn's Bluff overhaul?
After haven spoken to Vivec in the main quest, Temple members will greet the player (Greeting 7) with that the Archcanon has announced that you have been selected as a champion to meet Dagoth Ur. Here a specific greeting is used on the mainland to reflect that it is the Archcanon on Vvardenfell who made the announcement. This response is however ending up too high up in the topic list, making it blocking the response where the defeat of Dagoth Ur is acknowledged.
Ovaynel Mithryon (TR_m4_Ovaynel_Mithryon) has much more gold (1000) than what is logical for an outdoors merchant, especially given the stock of wares she is selling.
In the quest "A Rope Salesman", if choosing to buy it, the topic "buy this rope" will still remain in Vespertius' (TR_m4_Vespertius Pertin) dialogue. If selecting it, he will reinitiate the robbery attempt and try to sell another rope. I haven't checked whether this has been fixed.
A similar bug is present in "Ulves Heladren's Bathtime".
