Obviously in game I can correct it pretty quickly, but sometimes it happens as I dash which makes my dash arch in weird directions, and sometimes it moves me in the wrong direction just enough to where it'll cause me to miss the core.
Luna also has a bug where her dash doesn't lock onto the core and it'll cause you to dash straight up or down rather than at the core 2cm away from your face.
Same bug applies to her rocket as well.
I didn't record game play of those but it's easy to acquire if need be.
This video below is only of the auto run but you I did some dashes to sort of show how it affects the direction.
