Bug found in Training room...

Hey guys i know it sounds kindof lame to play training room and try to find bugs but here's what i found... If you go to the uppermost rightmost edge of the entire rift (which is where you'll usually get shot and be dead, due to the turret attack) and you go right under where the ray comes from, then toggle turret fire on, and off, you'd get the ray locked onto you, and it won't let go until you go across nearly half of the map. BTW if you go outside of the fountain turret's range, it will do no damage even if you toggle turret fire on. I can't figure out how to put a picture up here....
