Weird Critical Finish glitch?

The-Instigator

[09] Warrior
Believe me or not, but here's what happened:

I was testing out a new Sophitia CAS and was playing as Rock. On the 2nd round, I critical finished my CAS and during Rock's victory pose, the fore-mentioned CAS proceeds to crab walk towards Rock from the bottom left side of the screen, glitches him by pushing him out of the way, and crab walks away to the upper right side of the screen. Granted, I wasn't able to see it again when Critical Finishing other characters, so I was wondering, has this weird-as-hell incident happened to anyone else? Is this a glitch? Bug? Laziness in part of Namco?
