As long as I've played uo (since 98), I always co-owned all chrs to each house ( I only pay for 2 accounts). I recently set up 2 houses in this way. I noticed one of my players could no longer access Davey Jones locker at all. He used to be able to. I checked the house sign and it only showed 1 chr being co-owned. That surprised me. I then started the process of co-owning everybody again. Upon doing this I was informed that "this person is already co-owned". The players name doesn't show and they do have co-owner abilities. Please check your co-owner list to if you have a similar situation.
