I was leveling my maxxed alchemy shammy today and I used this flask. It's much like the old flask of the north from wrath, but it has on noticeable difference. I tried to reflask before the time was up and kept getting the more powerful buff already error. Is anyone else getting this too or is this just some sorta random bug? I like to drink the flask when I refresh my 30 minute weapon buff but only why I see this happening is cancel the buff and reapply which is silly.
