No Chocobo Porter available for Buscarron's Druthers

[Siberia]

Even though I have my own mount, I like to take Chocobo porters down to certain places if I need to go AFK really quick for a drink, some exercises, etc.

Ever since launch I've noticed that Buscarron's Druthers doesn't appear in the list of locations available to take a porter to from Gridania. Yes, I have the location unlocked, I can use it from Quarrymill to the Druthers, but from nowhere else. The porter also runs right through the Druthers on the way TO Quarrymill, so I know it'd be an easy fix.

It's not because it doesn't have an aetheryte, either. You can take a porter from Ul'dah to Vesper Bay, and I did so frequently when I needed to do story quests while leveling.

I have seen this bug on every character I have (I've gotten 4 to the point where they'd have this location unlocked, on two different servers, Balmung and Gilgamesh).

Any help with this is appreciated!
