After winning my second game on 1.02 I decided to examine the Epic Achievements that I noticed had been triggering as I played. (Press Shift-F3 in game to see your list of achievements).
It seems that some of them don't work, they are not awarded when achieved.
So I thought I would make a list so that others could report whether they had gotten the achievements or whether there are others that are bugged.
First, these are the ones that worked, i.e. were properly awarded when I earned them (or others reported that they'd earned them):
Win as Arceans
Win as the Mimot
Win as the Torians
Win as Festron
Win as the Drengin
Win as the Baratak
Win as Xeloxi
Win as the Iconians
Win as Altarians
Win as the Manti
Win as the Iridium
Win as Terrans
Win as the Drath
Win as the Krynn
Win as the Yor
Win as the Onyx
Win as the Navigators
Win as the Luxar Dominion -- Supernova only
Win as the Phalenoid Advance -- Supernova only
Win as the Intueri Aggregate - Supernova only
Win as the Cosmic Containment -- Supernova only

Second, these achievements I believe I earned but were not awarded, so they are probably broken.

Third are achievements for winning as the various civilizations. I have now tried all of them.
-All seem to work, but it took me 2 tries with the Navigators
Fourth are various other achievements. Either I know I didn't do these, or I think I might not have done enough to get them, so we don't know whether these work or not. Note that some of the victory type achievements are unavailable because that victory type is not in the game.

Finally are the achievements related to the Galactic Challenges. I haven't yet tried these so I don't know if they work.

Please post if you have found other Achievements that either work are can be confirmed as broken, or if you have better information than I about what is required to get the achievements.
