I took the new Quiver of my shared bank, so i could link it to a guildy on party chat. After linking the Quiver tried to put again in the shared bank, but i couldnt put there. Its says that now is bound to that character. I didnt equip it, not even got the warning message of the binding, but i cannot put again on shared bank.
No help with tickets, so i reported it as a bug.
Btw, you cannot equip a Quiver with double click, you need to drag it with the mouse to you quiver spot. If you double click on it, it opens and show the arrows that you are carrying.
