Two Rengar bugs

Gaining 5 stacks with Rengar's E sometimes will make the empowered version go on CD as well. Seems to only happen mid-leap.
The second bug is when jumping from ult to an enemy champion in the middle of their base gate. The leap occurs, but Rengar remains in the same position and just looks really weird. The autoattack will land, even as far as I was in the video, and procs my on-hits: Tiamat and Duskblade. Empowered E also gets delayed as intended, and shoots from my original (and final) position. Not sure if this is intended or not, but it looks really strange in game.
