As far as I can tell this is the first time anyone's found this, so I thought I'd document it.
Mutators were:
Game mode: Jump jam.
Arena: Cosmic.
Rumble: Destruction Derby.
Boost strength: 5x.
Ball max speed: Fast.
Ball type: Basketball.
Ball physics: Curveball.
Ball size: Small.
Ball bounciness: Low.
Ball gravity: High.
We think we narrowed it down to it being the basketball with this gamemode that caused it tho.
