[GAMEPLAY] Pyke - Ultimate glitch/bug

I have experimented abit with pyke and noticed something unusual regarding the interaction between his ult and flash:

If u ult behind him (that meanst NOT in the direction he is looking) and use flash during the channel, his ult will apply the animation of the cross-formed slash and dmg targets but he will not arrive at that location. He will stand at the location u flashed to. Dk if thats intentional.

EDIT(1): Okay, im not sure anymore if it always happens if one uses his Ult behind him, sometimes it works sometimes it doesnt. I have noticed that it works more "reliably" if you ult in the direction of botlane. Btw im testing this in the River at Drake in the Practice Tool.

EDIT(2): Alright, more testing, now i dont even land at the location after using my Ult, regardless of using flash.

EDIT(3): Okay, after even more testing: im not sure if this is actually a bug. I have now noticed that the Teleport towards the cross-shaped location always works if u damage a champion (or training dummy in the practice tool) so maybe it was intended?
