Rek'Sai Bug

I was Playing Rek'Sai jungle (second account) and i encountered a bug, check out the build in case its a build sensitive case. So whenever i'd activate my Q (unburrowed) I'd proc any on hit effects i had on myself (black cleaver and red buff specifically that I noticed). This made my damage taken extremely high Now because Rek'Sai is somewhat underplayed at the moment and it only happens for on hit effects i doubt alot of people notice it, but because i had red buff for a decent portion as well as black cleaver when i went to clear minions i noticed i was taking an absurd amount of damage and that stacks of the black cleaver debuff were being procced onto me.
