This link ^ shows the bug with Sliggy breaking it down. Clip was before the official Valorant account tweeted that the turret behaviour is a bug and the round will be replayed. Basically the Killjoy turret detected the enemy Omen player as he came out of door but when he walked back the turret spun back to shoot at Heaven and then shot again at Omen at door. This tricked the friendly KAY/O into thinking there was someone coming from Heaven when both players were at door, massively assisting FPX to win a 2v3 retake clutch.
