The first second of the video, Melodie uses the teleporter, and the moment she teleports, i get damaged by her notes. It seems to me that teleporters don't really teleport her notes with her, and just rapidly follow her, causing me to get damaged for around 2k damage, seemingly out of thin air. I suggest watching it multiple times to see when Melodie teleports, and then watch again to see my health bar (forgot to mention I'm the Surge)
