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).

Fighters's guild in Andothren first quest issues: - Hjaskar can fall off the dock into the water and drown (I couldn't find him until I got a note he died and guessed!) - You can steal the 500 drakes from him and then get the 250 by talking to him, for a total of 750 drakes. He had even more money than he wasn't letting on! (To be clear, he should tell the player, "Hey, you stole my money already!" and attack or whatever. But he doesn't notice you stole from him, and still has drakes to give.)
The NPC Garo Varsel in Tel Gilan will pretend to be in town to see the sights and ask you to track down his friend Temus Lorthus, who upon being found will inform you that Garo is actually an assassin sent to kill him. However Garo will, from the start, openly tell the player that he is an assassin if they select the dialogue option about his trade. This dialogue should probably be changed so that he lies about his profession instead.
