Ya I noticed something similar earlier on live build 4.17, but I thought I was just doing something wrong since I don't play Nid often. Just now created a custom solo match to test it out, and she would inconsistently Swipe directly in front of her while moving sometimes regardless of mouse cursor position, and sometimes would attempt to turn and swipe towards the direction of the cursor (while she is moving). I say "attempt" because she sometimes would not turn all the way. Swiping while she was stationary consistently made her face the direction of the cursor to Swipe; only while moving was it an intermittent problem.
Also, when reporting a bug, add the tag [Gameplay], [Client], or [Crash] as appropriate to the bug in the title. This is explained to the left here, for making it easier for the right Rioter to help out and track it.
This bug is now occurring in the live patch. As a nidalee main, this is very frustrating as it takes away a significant amount of damage to miss your swipe on a hunted target for no reason.
