During the clearing of today's EDZ bunker, one of the Heavy Frames I spawned became invincible through an unknown cause. The frame went into the self-destructing animation, but instead of exploding, it kept shooting and dealing damage through that alone (Explosion animation did play along with the particle effects but didn't deal any damage, frame kept shooting as the animation was playing). I have been unable to record it during combat but I'm attaching a video of it afterwards. The frame didn't despawn until I left the bunker completely.
