Nah, totally intended mechanics. Kappa Seriously though, looks like a VHC / Vertical Horizontal Conversion (AKA your horizontal speed getting converted into vertical speed, useful in TASes; RTA uses a simple form if it, super bouncing). Not sure exactly how it happened here, but funny to see nonetheless LOL

Correction: HVC, not VHC. Horizontal/Vertical conversion. VHC is your vertical speed getting converted into horizontal speed.
