Shen Ult Issues -

I shen ulted an ally possibly as they were dying, they never received my shield My ability went on cool-down and I did not receive an assist for the kill that was given after.

Later in the same game I ulted an ADC that died before my ult could finish. I never arrived into the battle (which is normal)

However, I never received assists for the kills that happened shortly after the ADC died. He participated in the fight, and I applied a defensive shield to that player which usually grant assists.
