Turret bug

I've found many times that if an attack or ability kills it's target while both are under turret that it won't draw turret aggro, which is what happened. Not sure why that is tho.

I don't see why the tower would focus Illaoi here, Akali Qs Singed and back out of tower range so she doesn't take aggro. Then she goes in on Singed which does take tower aggro while Illaoi kills singe. Akali dies after Singed is already dead, there's no reason the tower would change targets to Illaoi after he already died.
