Apparently there was a fairly serious bug with Alchemy and discovering potions/flasks/transmutes last night, so Blizzard has hot fixed it to no longer be possible to make a discovery for now.
From Tseric:
We have been working on the resolution of a serious exploit in game which has led to certain consequences that we wanted everyone to be aware of. A hot fix has been recently applied to the alchemy profession, with regards to discoveries. For the time being, we have disabled all chance of a discovery, until we can implement the proper fix through a patch , as we can not resolve this matter solely with hot fixes. We apologize for the necessary but temporary removal of discoveries, and are working to have them re-implemented with an upcoming content patch.

It does sound like that was the bug, Dmaw-Erock.
can anyone confirm exactly what it was, it was talked about in the thread that they were making potions with full bags and discovering new ones without wasting the reagents. can anyone confirm that is what was happening.
