So, on the PTS I got all the storage trunks and coffers I could, and put them in my primary residence (which is also the guild hall).
My husband got them all too, and put them in his house.
When he goes into the guild house, he can see all the coffers and is given the option to use them.
Except when he tries, he gets a message "You are not allowed to open storage you don't own."
I believe that with the fence, you can use one in someone else's home if you already have a fence.
My question is, will storage in someone else's home be usable if you have a similar coffer, or not? It is shown as usable, but I'm not sure if the non-usability is a bug, or not yet implemented, or just put there to annoy.
