Mission: Armatus (Labs Disruption)
Matchmaking: Solo
Issue: I has just killed the Gruzzling clones. A second later, I killed the main Gruzzling as it cast its slowing ability. The Gruzzling died but the sand persisted, and since I was in it, the slowness as well. I loitered around the area to see if it would eventually go away and then decided to run away from it. The issue continued to persist until I let something kill me. Afterwards resurrecting, both the slowness and sand had dissapeared.
I got a recording[Link] but I may not be of much help. I started recording AFTER killing the Gruzzling.
