Bug occurred on EU at around 10:25 EST
Based on my knowledge, heli attacked someone (not sure if sleeper, away, or what) and either killed or failed to kill them. At that time one other individual was firing at heli trying to draw its attention.
Heli was hellbound on making sure the original person was dead and so was circling above for a while. Whenever the heli was tagged nothing would happen. Heli started smoking, then *poof*! Vanished into thin air.
I wish I had more info than that. Sapnu Puas has also reported this on discord and may have more info.
