Small glitch with Blue Nexus?

I have played 2 games recently where the enemy teams had a Jarvan IV in one game and a Darius in the other. When they were both near Blue Nexus, there was some weird glitch where they could drag or pull people into their ult or ability ranges. I have a clip of the Jarvan IV doing this with an Ult, I was outside the ult range as Gangplank and somehow got sucked into the center and lost control of my character for the duration of his ult. Gangplank when I tried getting him to move towards the fountain instead started running towards the team while in the Jarvan's ult. The Darius game I was playing Graves where I was on the opposite side of the Nexus and Darius could pull me and 2 others just by pulling the closest person near him. My friend who was in this game noticed this and both of us tried to save the game clip to our computers but it would not work. I have tried posting the Jarvan IV game clip but for some reason the link does not go through on this. Is there a small glitch with certain abilities on some Champions around Blue Nexus?
