Enemies killed by Revenant's "Reave" do not contribute towards extermination objectives.

[Nomnivore1]

As titled. Killing enemies using Revenant's "Reave" to take their health away does not add progress towards the objective of Exterminate missions. Easy to replicate, build for enough power strength to take >100% health from thralls with Reave, enter an Exterminate mission, and enthrall then reave some enemies. When i did this, the enemies killed by Reave did not contribute towards the objective. This happened across multiple missions, in the steel path and regular star chart.
