The sttarting script for the quest "Muskflies in Bal Oyra" does not begin until the player arrives in one of the Bal Oyra cells, causing quite a problematic behaviour if first arriving in Bal Oyra from the road. The script makes all the NPCs disappear, but this doesn't happen until you have taken a couple of steps into the town. I was even talking to one of the NPCs at first and then they all just disappeared, so this is both confusing and unrealistic. This should be solved somehow, perhaps by starting the script already when the NPC arrives in one of the adjacent cells. Alternatively one can use one script for removing the NPCs which trigger in adjacent cells, and another one for spawning the flies and starting the quest, which triggers when entering the town.
