Zed's shadow doesn't cast q

I want to apologyze about my english by upperhand. For zed main players this bug is easy to notice, following i m gonna write an easy step by step description of the bug: 1-cast w 2-cast q as fast as possible, before the shadow gets to the position you selected 3-then recast w to teleport to that location asap, it is very important that the time btw completing step 2 and 3 must be 0.1 s [that s why i said this is ez for main zed players] 4- and what happens is that the first q, that one that you shot, travels its original distance but the 2nd one , shadow's q, is not being shot from where you positioned your w, is being shot from the original position where you casted your w.
