Just watched it again it shows the bug specifically after 4:00 I don't know why I wasn't more specific as if you're not busy or something, my apologies. Before that I was just testing other factors. I'm not crazy... :D
Not crazy, just not right either. :^)
Transcript from 4:00 -
(Painwheel grabs) "So like, right now?"
(Robo ground techs) "Control-Z."
(Painwheel responds to the tech) "That's cute!"
4:11 -
(Painwheel grabs) "Barf me out!"
(Robo ground techs) "Buffering."
(Painwheel responds to the tech) "Bummer!"
The ground-tech response doesn't happen at 4:15 because you dashed, so Painwheel interrupted herself with the dash VO.
But it happens again on the last throw, right after that.
In conclusion, the game's worked this way for several years, every character has ground-tech response clips that they play if they're not playing other VO.
Catch ya on the flipside...
