[dev 1018] Remove the empty Retainer

Hello Devs, Moderators and Yoshida-P!

PROBLEM: I can't summon the Retainer on each floors in Ul'dah Market Warden on the Selbina server anymore since few days, because it's full! >.<

SOLVE: My suggestion to avoid the overcrowded on specific floor of the Market Warden OR unable to summon the Retainer in Market Warden: If the items are completely sold and the bazar icon over the head is gone, so please disappear those retainers immediately from the floor!

Thank you for the reading! :)
Kind regards

They've already said they're going to implement something like this. No specifics, but this would be the obvious choice.

Just remember, Removing Empty Retainer along won't solve the problem. A #@#$ could be sell something worthless for a million Gil. Then his/her retainer will be always there.
