Darius hook goes backward after flash (just like Kassadin and Nid cone-shaped abilities after jump)

Kass and Nid are disabled because of a bug, presumably the one I've seen reported where their cone shaped ability goes backward after they jump. It also happens with other cone shaped abilities after flash, in my case, playing as darius trying to use my E. See it in action in this youtube video:

Server: NA • Type of Bug: in game bug • Description: Darius E goes the opposite direction it was intended when used immediately after flash • Video / Screenshot: http://youtu.be/L8x2q-u6o4Y • Steps to reproduce: pick darius, level E, flash forward and immediately try to grab forward • Expected result: Darius E should sweep an area in front of him, where the cursor is • Observed result: He will actually turn around and sweep directly behind him instead of in the direction you cast. • Reproduction rate: Happened all three times I tried to do it in a live game before I noticed the pattern. • System specs: Intel 4770k, nvidia gtx 660 ti, latest drivers, windows 7
