I had been using quick slot for health potions which are essential INMHO for battle. But for some reason these are not working. I see them slotted. however, during battle the slot shows and empty bottle instead of what I have slotted. this is the case with every single one of my 4 toons from the highest of over 210 CP to the lowest level 18.
Is there some mysterious setting that could be preventing the use of quick slot that I might have accidentally triggered? Or is this game seriously bugged?
