Apologies if this has been posted before, but...
After visiting the Underdark, markers for characters and locations appeared on the surface map.
I don't think they should... it's rather confusing because it appeared as if Zevlor was standing right next to Omelleon (or however his name is spelled).
Even if they are technically next to each other - just separated vertically by several hundred feet, it seems rather odd having Underdark markers on the surface map.
