(GAMEPLAY) Tahm Kench won't use his W on ashe.

So I was playing a game as Tahm Kench and was in a duo with an ashe. Early game my w AKA the "eat your ally" ability was working just fine, until we got ganked and i noticed i couldn't use my w to take my adc to safety. I shrugged it off at first but it didn't go away and the whole game i couldn't use my w on my adc, which is a massive tool that is crucial to playing tahm kench. My w worked fine on all other allies however. The ashe had the marauder skin if that helps.
