[GAMEPLAY] Nautilus Ultimate does not work when Kled dismounts Skaarl

I was in a nemesis match yesterday, against an enemy Kled. I ulted him, but someone else took out Skaarl, and as he jumped off of Skaarl, the Nautilus ulti disappeared. The blue target circle was still around him, but there were no explosions following him and he never got knocked up. This happened one more time during that game. I don't have a video because I don't have any recording software.

1. Have Nautilus ult Kled, but have Kled low enough to take out Skaarl.
2. Before the Nautilus ulti gets to him, take Kled off of Skaarl
3. There ya go, ult won't work.
