Reverse Continuum Bug

This is the 2nd time it happened to me:

If you're not familiar with the mode, the continuum (electric, blue sphere) is supposed to inflict damage when you run outside of it (or when it shrinks faster than you can stay in its borders).  In this case, you can see two of my opponents KO'd by attempting to stay inside the continuum. 

I should note that the beginning of these games are normal and not reversed.  For whatever reason causes the glitch, this damage reversal occurs when the continuum shrinks way too far and way too fast (it typically shrinks in increments instead of going from full sized to naught). 

It's like the game/round itself took too long or ?? Iono?

I think @dwooten77 witnessed this happening with me once as well but it might have been someone else.
