T_De_Set_X_DecalWall_25 on top of Measurehall's flickers using MGEXE without distant land. As T_De_SetHla_X_Narsis_B_19 is a single baked building, maybe replacing them with decals would be in order. But as it's so high up, just moving alpha slightly aways from wall shouldn't be noticeable either.
In the quest 'Good Neighbors, Good Fences', you are supposed to steal a midnight agate from the second floor of Nevusa Falen's shop. I cannot locate the midnight agate. I believe there might be some interaction with another quest, 'Trouble Brewing in Andothren', but that's based on nothing but a hunch.
Waterstrider's hitbox is so large that talking to nearby NPCs is pretty much impossible without console commands (like TCL) and the player can't travel by waterstriders in northern Telvanni towns (Gah Sadrith, Port Telvannis, Llothanis, Tel Ouada).
None of the map 2 vampires belong to any vampire clan, despite having scripts associated with the Vanilla clans. This is true for all NPCs with the scripts T_ScNpc_Mw_Map2VampAundae, T_ScNpc_Mw_Map2VampBerne, T_ScNpc_Mw_Map2VampQuarra, TR_m2_Norem_Inte_Vamp1_sc, TR_m2_Norem_Inte_Vamp2_sc, or TR_m2_Norem_Sanc_Vamp_sc attached to them. For some of them, there could of course be a reason for it, but it looks like an oversight to me.
The name for T_Glb_Fau_BatDs_01 is spelled "Disesased Bat", should be corrected to "Diseased Bat".
There is an inconsistency in the blood texture used for mummies. T_Mw_Und_Mum_01 and TR_m1_aran_mummy (from TR_Mainland) use red blood, whereas T_Mw_Und_Mum_02, T_Mw_Und_Mum_Rise_02, and T_Mw_Und_MumPl_01 use dust. These are definitely similar enough to use the same blood texture (choose whatever is reasonable here).
