(I understand this is a Steam related issue, I'm just wanting to know if anyone else has had these problems or if anyone knows how to fix them.)

So I bought this game about a week or so ago and have really enjoyed it so far. My only problem with the game is that certain achievements like the slaying of the Elemental World Bosses do not seem to register on the steam achievement. 

I've killed Abeix about 4 or 5 times so far (different games completely), I killed Delin today for the first time (he was right beside where I started 0_O) as well with Torax. Vetrar I've slain twice in 2 different play through's. I've killed these bosses on I believe to be one of the Large style maps (it's the exact same one as the Legendary Scenario). I'm not sure why but I do not recieve credit for killing these bosses at all, the other ones I have not listed I have killed and the game gave it to me fine.

I was wondering if the achievement bugs out if I save the game either during the match  and reload it either later in case i'm doing something else or because of I messed up and accidentally got a regiment of hero's killed.

If anyone has any suggestions or info on this any help would be greatly appreciated.

Oh, I was wondering if anyone knew how to:

Recruit Kasst (Brood Warden Champion)

Recruit Gallowman (Lord of Necromancy)

Wasn't sure if they were a Fame thing like the Troll and 2 Fallen's.

Thanks.
