Tahm Kench Devour Bug

I have not tested it when just scooping up a minion, but when using a rapid Q+W+W to clear a wave of minions quickly, Tahm will pull the minion to him and play all the sounds of the minion being spit up, but it will simply land at his feet and do minion things, rather than go flying to the other minions and do the damage I was promised when I began spitting minions at eachother.
