Pyke's ultimate reset gets clipped after using Stopwatch/GA/Zhonias(?) [GAMEPLAY]

Hey, at first I just thought I had ran out of the reset timer, but this has happened now several times.

So I earn ultimate reset with killing/assisting and then use Stopwatch/die with GA, just to realize I've lost my ultimate reset and it's on CD now.

Wasn't sure if this was intended or not, but seemed weird to me..

Thanks
