Master Yi Bug

I've experienced a game where i always had the same bug with yi. Everytime you jump/ smite at the same time a camp in the jungle, they do not react and their hp is always repoping (as if you were leaving the camp without killing them). This happened to me yesterday and it has a 100% reproduction rate. Juste A-strike (q) smite at the same time. I had build devourer on yi and did not check if it was only with that item or not. Nothing changed when my devourer got fully stacked. It can also be used to "cheat" as you regenerate your life with your life steal.
