Blitzcrank Pull

I was just playing blitz supp, and I was going for nid under their tower. I died from the tower, but nid still got pulled. I know it happened, cuz the opposing teemo also saw it happen and I know it happened after I died because my screen went black and white like it does when you die before showing nid getting pulled, so I know for a fact that either its a bug. Also, I didn't see my hand go out and grab her, so I'm sure that's supposed to happen but not the pull.

Don't know if it works with thresh and/or naut
