[Gameplay]Blue Buff Patience Bugged

I was playing a game of jungle Sion, and every time I knocked up the Blue sentinel with a fully charged Q, he would immediately lose and reacquire aggro on me, which as you know, losing Aggro on it causes it to lose patience searching for a new target. In 3 Q's, it entirely reset on me. I didn't leave it's leash range, I didn't have somebody with me, this is a bug.
