Teemo shroom bug!

this bug has happened before many times. i discovered a bug in intro bot game where it happens every time u pick teemo and reach level 6 plant a shroom and it explodes (the bug is show i the video link). i dont know that does it have anything to do with the game mode or the items i have bought. i have had dark seal on every game ive played. i havent tested this bug in other gamemodes so i dont know about those. basically everytime your shroom explodes it creates a new one under it which explodes instantly. the number of explosion is random but i think it has something to do with that is someone standing on the mushroom and exploding it constantly ive reached explosions from 2-21. sometimes the shroom explodes more than 10 times after the someones left the triggering spot. i hope this bug report helped you out. hope you fix it soon. happy to help :)
