My assumption was that Vesper was only added to the menu so (new?) players knew they could get to either town, but still linking to the single gate. Have you actually seen a new gate in Vesper?
Vesper amd Minoc have always shared a moongate. Nothing dumb about it. We could call it Vesnoc. Minper sounds too forced.
eh, I just think the approach was dumb. We dumped moongates everywhere else, then updated the menu with all the city names. It could have been communicated clearer, and the menu could be as well (it's also butt ugly, but that's another issue)
