Bug - Normal Noise-Cancelled Brass Knuckles Knockback

[Krazete]

In a recent High Tide Prize Fight, my opponent's Resonant Evil (opRE) began the match by dashing forward and using Brass Knuckles. My Resonant Evil (myRE) noise cancelled that, which stunned opRE. myRE began punishing opRE with the basic ground combo, but right before opRE's stun ended, myRE got knocked back all the way to the left of the stage as if he was hit by opRE's noise-cancelled Brass Knuckles.

I know I'm not mistaking it for a burst because it happened before the stun ended and because a burst knocks back Big Band by a much smaller distance.

I didn't see whether myRE received any damage from this.
