Summary:
Sparks can grief teammates by destroying friendly deployables with her REVIVR gun. When you aim at the deployables, it will still have a blue “friendly” X over the crosshair, but you can still damage them. No XP is awarded for doing it.
When this happened:
First a few days ago, but was able to replicate it today (July 17)
How to replicate:
Have a teammate drop a deployable (Aura’s Med Station, Proxy’s Mines, etc), and shoot it with your REVIVR.Depending on what they dropped, it may take a few shots, but you will be able to destroy it.
