Brand's Ult is buggy

Recently I have been playing a lot more of brand in this season and I have been noticing that his ult sometimes doesn't bother bouncing between targets and only disappears after the initial impact. There would be instances such as where I would ult elise in her spider form where she has 3-4 spiderlings around her, yet the ult just dissipates after the first contact with elise. It's gotten to the point where i'm noticing this occur about one-third of the time that I use brand ult and it has become enough of a nuisance to lead to lost fights and spoiled games.

This bug with his ult disappearing has occurred with several other champions that were clearly in the middle of a creepwave or next to a teammate.
