Rolling mid air issue.

[YinYin]

i'm afraid that won't really work all too well

unless you are open to editing the falling frames of every opponent this shall work on
(offset in y direction for both: flute itr and a bdy inside the falling frame overlap only with each other)
that way it will only work on the knocked out character

wait there is one more thing you can try
fall: 70 on the flute itr as well - that might make it only work on a falling character (maybe - never tried it)
