False positive on Ethereal Manor

[Nundah]

Ethereal Manor always shows up in the World Analyzer. Sometimes it's at the bottom of the Losomn list with (DLC1) as the location. Other times it is listed correctly at a compatible location. Either way, the manor does not appear in my game.

The manor appeared when RSG said it was in (DLC1) for the location. It seems that the manor may or may not appear regardless of what RSG says.
