Potions also fail to consume even when you hear the sound of it only to see 5seconds or so later that you didnt actually drink it, ive had this "bug" for 3-4 days now and people on my friendlist say they have had it even longer then that. (this is in cyrodiil, but population has nothing to do with it because i have it in the early morning when there are few players in pvp and even in Shor in the evenings whe pop is low on all alliances)
