So I am now stunning a shielded player instead of being pulled towards them...
First my Fire ball redirection, and now my portable hookshot target 
I get that changing 1 thing can affect 60 other things... but I think multiplayer interaction need a good look at.
Fireball redirection only works with friendly fire on, but that causes shielded players to be stunned now...
Turn it off and I can hookshot to a shield, but fire balls then ignore the second player
Either the Shield, Hookshot, or Player "friendly fire" has a bug resulting in unexpected behavior when all 3 are combined
