Recipe disappeared from Alchemy list

[Earane]

Yesterday I purchased a recipe (Transmute Elemental Fire) from the Thorium Brotherhood NPC in BRD. It showed up in my alchemy list yesterday, but today it is gone. I've tried the thing where you delete your WDB folder but it didn't solve it. Is there any known solution to this problem?

Thanks in advance

This is not cool. I freaked out when I saw this missing from my list, because I just bought 25g worth of Heart of Fires from the AH.

Why is there no official announcements for these? I was using the transmute just last night, and would like to be able to plan around big changes like this.
