Just wanted to confirm (near the top of this thread) that this indeed turned into http://www.wowhead.com/?item=44629 after the 365 days. Apparently it is a one use item but I do not intend to test it, I intend to keep it just in case they fix that or make it not suck. Additionally the http://www.wowhead.com/?item=44625 turns into a http://www.wowhead.com/?item=44627 and my http://www.wowhead.com/?item=44623 and http://www.wowhead.com/?item=44632 turned into a http://www.wowhead.com/?item=44625 and a http://www.wowhead.com/?item=44626 EXCEPT both have a duration of 0 (zero) days.
