Is there a mod or in-mission effect that deactivates exotic perks like Rat King and Crimson from triggering as they are supposed to? During reset and the following Wednesday I attempted to solo the Variable quest. While using Rat King, or Crimson I noticed that during the final phase of Brakion that neither exotic's perks would trigger on Kill/Reload. Is there an intended reason for this or did I happen to stumble across another bug?
