Most (all?) topics with a ShowMap "Old Ebonheart" command (most notably the topic "Old Ebonheart". I have not checked if there are more) do not include Ebon Tower, making only the three Old Ebonheart cells show up on the map. Ebon Tower is such an integrated part of the city, so this does not make sense. I would therefore add the line 'ShowMap "Ebon Tower"' where applicable.
The path grid in Raal Grotto only covers the area around the NPC. There is no path grid in the rest of the interior, which could cause issues e.g. if bringing companions in here.
Quite a few interiors in Roryn's Bluff section are either missing their path grid, or have one that only covers part of the interior. Moreover, I found one interior where the path grid has been shifted outside the possible paths in the current implementation (I suppose it was overhauled, but the path grid was not updated accordingly). This survey should cover all dungeons in the section file, but I have skipped most dwellings.
Among the 'latest rumor' entries for Gol Mok, there is one that reads: 'I wonder what's inside that Dwemer lighthouse above Andothren.' This should be removed, as the lighthouse was removed.
After the completion of the Stendarr's Tower Haunting quest with the removal of the ghost, the ghost whispering SFX continues to play in the tower which makes little sense. If possible, the SFX should stop playing in the tower after the ghost has been removed.
Some of these are probably fixed by ITO or will be. Plenty aren't. I cut out all the rows that looked correct, but some of these might still be correct. All the ashlander ones are definitely problematic except maybe the ones in the Valenwood mission.
A guild guide is a spellcaster of the Mages Guild who provides magical transport for a small fee. You can only travel from one Mages Guild to another, but it is the fastest way to travel between Vivec, Balmora, Ald'ruhn, Caldera, and Sadrith Mora.
Should probably have a map specific response mentioning whatever network is most relevant. Alternatively a generic entry could be added that simply removes half of the last sentence.
