Been experiences weird glitches regarding two special moves, the Piercing Dash and the Whirlslash. Happens in both Stable and frontline. Sometimes when I use the moves, other sprites seem to glitch into existence. It only lasts a millisecond or two, but it's just noticeable and freaked me out the first time xD I think it's something to do with effects colliding, and the game bugs out. I'd screenshot it, but it happens too fast. For example, when you fight Vilya for the second time outside the Headmaster's room, when she does her dash attack that leaves behind transparent versions of herself, if I use the Piercing Dash at the same time and we collide, sometimes the glitch happens. The Whirlslash seems much more random, and I've had much less problems with it.
