Whenever Jazz (haven't tried with Lori) lands on a vine whilst copter-earing, there is a short delay before he can jump off the vine again. Worse yet, instinct (when playing with Spaz) dictates that you would press jump instantly off a vine usually in competitive play, but with this you end up getting stuck for even longer as it keeps playing the copter sound (presumably it thinks you're still copter earing).

Can this be fixed?

Fix will be available in 5.7.
