Same happened to me a few minutes ago.
I was Playing AFK and trying to get both Achievements.
Second round i fought against the Sir Finley in our Lobby who had actually 0 (zero) Minions and so i didn’t lose any health turn 2. Turn 3 i stayed AFK for the achievement.
Interestingly the Sin Finley player stayed first Place for the whole game without losing any health. The battlehistory only showed him fighting Mr. Bigglesworth over and over again.
In the End it was only three players left. The named Sir Finley on 1st with 40 health, a Lich King and me. I fought the Lich King twice (shouldn’t be possible if Finley really still was in the game) in a row and beat him both times.
After that i got the 2nd Place Announcement and +300 Points (1st Place?).
Through this i missed out on both achievements.
@Devs: Pls fix this or at least refund me the two missing achievements bc they really are a pain in the a**. Thx a lot.
