if kragg makes a pillar at a really specific horizontal spacing (vertical spacing doesn't matter) where the edge of the pillar just barely overlaps ledge, grabbing ledge will break it and kragg WON'T go into special fall. this also happens if you are grabbing ledge and THEN kragg tries to spawn pillar at that specific spacing. i've attached a clip of this happening in training mode, as well as a clip of it in a real match.
