If I join my friend's guild, place a port clicky like The Umbral Plains Bowl in the GH, and then leave that guild will the item i placed stay in that guild hall? Figured I'd ask before trying it. Thanks in advance.
It stays. If you delete the character then it gets deleted as well. Hint: You don't need to be part of the guild to place items.
They stay, and if you want them back you can visit the neighborhood plot where that guild hall is to bring up the inventory window and grab your stuff from there. Or if your anchor is still in the guild hall that's even easier.
