Possible recall bug

I have noticed several times today that when players go to recall, after maybe half the time has expired, they literally disppear from the screen. I searched the 6.15, 6.14, and 6.13 patch notes for anything about them extending the already small amount of time at the end of a recall that prevents a cancel because of enemy damage, but this is NOT that. They are becoming un-targetable and disappearing as well. I can still hear the recall happening, though.
