Malleus Monstronum "Achievement Bug?"

Issue Description
On the map Relay Station TRS-150 on T-4 Heresy, my friends and I were going for the achievement Malleus Monstronum and found a Demonhost near the final airlock toward the last area in the mission. Our Ogryn tanked the host while our other Psyker and Zelot handled any Dogs, Trappers and Mutants that came our way. We did NOT get any other hordes or other monsters at all. I did all of the damage to the Demonhost using “Brainburst” and NOTHING else other than 2 bullets from our Ogryn to start the encounter to get aggro and did not get the achievement for killing the host with more then 90% damage coming from Brain burst. This was quiet annoying to have happen where it is such a difficult achievement in the first place. Any assistance that could be provided would be super appreciated. Great game so far Fatshark (3) classes max level and (1) to go!!
