I've already put in a ticket on this and got "We'll look into it thx" as a reply, so this is more to let other _players_ know than anything else: The buffs Sayge at the Darkmoon Faire gives - the "Sayge's Dark Fortune of <foo>" ones - are currently vanishing on logout, poof. It does not seem to matter how much time they have left to run or which of his buffs you got; if you log out with one, you'll log back in without it. I know this wasn't doing this for last month's Faire, so it's something that broke since then... Just a heads-up.

We are aware of this issue, it was caused by a change to several zone-wide buffs (such as the buffs from killing onyxia).

These buffs will be changed in the next patch to be removed only when zoning into a raid instance.
