One Head Down trophy bugged?

[RedlChris-_-]

Hey everyone! 
I killed all the cultist leader from one section, but still didn't get the trophy.

 

Any idea?

 

Thanks!

If the cultist leader you killed was Nyx the Shadow during the Ashes to ashes quest in Athens, then the trophy will unlock at the end of the sequence. Same thing happened to me, the trophies for one cluster and sequence 6 popped right after each other.

Just continue playing for a bit, it should unlock just fine. 

 

if it was a different cluster then I have no idea
