Master Yi Q+Smite bug

If you use master yi's q and you smite mid-way while you are in the so called "invulnerability", the jungle monster that you attack won't find it's target, while the other minions around it (except gromp) will attack you, but the main target ( wraith, wolf, gromp, red buff, blue buff, big golem ) won't be able to find it's target and will start to regenerate hp very quickly and will just stay in one place EDIT: This bug is on live as well
