[GAMEPLAY] Urgot Ultimate Did Not Execute?

In this video I ult Nidalee as Urgot and the execute damage does not go off.

I suspect this has to do with one of the following:

1. The recent change that allows Urgot to walk while he is ulting, or
2. His ulti not properly applying damage while in bushes or while the champion is not visible to Urgot.

The replay file for the same game is included. As a side note, can we get LP back for losses in ranked?
