In the Unwell Traveller, a misc quest in Bodrum, Wesencolm seeks to get cured of a common disease. In his dialogue, the town priest (tr_m4_golvyn_saryon) offers to teach you a healing spell. However, he neither teaches it to me in dialogue, nor does he have spell for sale. Either of these two options should be added.
Having implemented most of the Hlaalu questline, I finally gav the released product a playthrough (but without testing every path to each quest). These are the issues I found:
The pathgrid outside of Oran Plantation seems to have been set up around scenery which are no longer there, there are 2 circles of dead space with no path nodes but the pathgrid goes through the big floral arrangement in the middle of the courtyard, resulting in NPCs walking over the plants and into the tree. It looks a bit strange.
Although I wrote this quest, upon replaying it more than a year later, I find some of Nalvos' dialogue to sound too contemporary. In particular, the topic "problem with the statue", there are several mentions of a "pub", which is not a word used often in TES III. It should be replaced by "tavern" or "inn". Second, after being upset that his drinking buddies aren't coming along, he asks you to get Olvys to cut off their "beer supply". This being Morrowind, "beer" should be replaced by "shein" or "sujamma" or whatever else is more appropriate.
This bug was apparently fixed in 21.01, but again appears in 22.11, as Cheeya in Nebulud cannot be freed once again, as she doesn't provide the speech to go free.
I spotted several floaters along the river in the Aanthirin Region (the cliff has probably been redone, but some rocks/vegetation remained to their previous positions).
