A thing I noticed in the OE Legion Tower. At the top there's a tapestry with a map of Morrowind. In the map are a series of nails used to mark locations. If you activate the nail you can't pick them up but you get a bounty of 5.
I would probably have them set to no owner instead. Unfortunately skyrim and oblivion have similar maps and activating them mark the locations on the map for you, I think a lot of people are going to make the same mistake I did.
Suggestion from Rot: script them with ShowMap to add the locations to the players map when activated
