Morgana Ult Goes Off after dying. [GAMEPLAY]

In the clip, you can see that Morgana ults before she dies and after dying, Shaco walks away and is still hit by Morgana ult second proc, dying because of it. I do not know how often this bug occurs, but it just happened recently in my ranked game and this is a very dangerous bug to be left in the game. I have never seen this bug occur prior to patch 10.1, so I do believe this was unintentionally added into the game.

Note: My brother and I tried recreating this scenario multiple times in a custom game. It seems to happen when Morgana ults, killing the Shaco clone which consequently kills the Morgana as well. The chain proceeds to tether as though nothing is wrong. The following clips are the recreation attempts we did.

The third recreation shows that the tether is also now infinite range.
