Soo when I am using interfaces to let blueprints talk to each other I have to specify what blueprint the message will be talking to. Great. So how do I get the player controller without having the index mucking things up? Basically I am now dealing with a bug where player 0 always dies even if he kills the other player. Please tell me there is a solution to this that doesn’t involve magic.
There is a node called “Get Controller” which returns the controller of this pawn (character is a child of pawn).
This will return the owning player or AI controller which controls this specific pawn.
Cheers 
Yep that was it! Thank you so much its now working correctly! I am so close to setting up a fully functional game mode I can taste it!
