[GAMEPLAY] Alistar 8.5 bug

After patch 8.5 anytime I land a headbutt on any enemy my trample goes off automatically. I went into a practice game to test this and found that after I queue my trample with headbutt, it will now automatically use trample anytime I land a headbutt. This occurs 100% of the time I use headbutt on its own, occasionally it will not occur when I queue pulverize with headbutt.

This is quite annoying because when I go to headbutt an enemy away to peel, it wastes my trample cd and mana.
