Delayed Jump after Falling off ledge

[DavodGitHub]

(As of right now, I have been unable to figure out why this happens. Please let me know if you figure it out.)
Sometimes, if you walk/run off of a ledge, you are unable to jump until you have fallen for a while. I have seen this happen a lot, and it seems to be random. Sometimes it happens only once during a match, other times it will always happen during a match. I currently cannot do this on purpose, I will update you all if I figure it out. UPDATE: It seems like if you fall a certain distance, it won't allow you to jump. The distance at which this occurs and whether or not it delays the jump still seems inconsistent.
