Yasou's Ult

For the past month or so I started to notice a change in Yas's ult. For some time I thought it was me. That I just sucked as Yas again T-T so I wasn't bothered by it for while. Sometimes when I ult as Yas I would only pick up one person while the rest just fall to the ground and attack me. I've been harrased by this and I really did think it was just me and I was ulting incorrectly. But today in Rank I was actually able to test out my theory that maybe it was an actual bug. Chogath's Q picked up 3 people. Kassidin(right), Volibear(Middle), Tahm(left). Before someone says that I ulted incorrectly that I was too far away from the rest and couldn't pick them up or say that they had individual knock up times they didn't. Its a Cho'gaths Q. Furthermore I ulted only up Volibear. The one straight in the middle, so Tahm and Kassidin just fell straight through. I know this isn't a major ult but its been here for such a long time. And was hoping it was noticed and can be fixed. It took like 5 moths to fix TF's stun going through Yas's wall. Don't let it be that long for this please. In a perfect knock up of 5 I'm am scared to ult now because I may just pick up one at a time and the rest attack me. Happened before* Still thought it was my poor skill back then but I realized this isn't the case. Also this isn't the case for all the time. Sometimes I can ult more than one but its random. If there was a recent change in Yas's ult please forgive me for wasting your time.
