Withdrawing Items from Expired Retainers

[Zetsumei_Tsunarashi]

I think they could have a system similar to the resident caretaker NPC who holds your items when your house is auto-demolished. If your retainer sub expires while holding your items, everything gets moved to an NPC for X number of days where you can retrieve everything. After X number of days, everything is deleted (same as housing) so you can't just hoard everything there forever.

I do agree with the above posters though in that it's probably just best to remove your items before your retainer sub expires. Perhaps they just need to make it more visible in-game when your sub time on retainers will be expiring.
