I see you are talking about ninja disconnecting, I am not using ninja so I have no idea if he hunts or not. I will test ninja though. Well pathfinding works on him but yeah he disconnected after the fifth kill lol.
Works fine now

I knew what the problem was pathfinding works fine on ninja now for me and fatalstrike is also fine with pathfinding system. I can't believe after three hours you guys couldn't figure the problem out.
I should also add that the pathfinding system I use is not perfect either as it has always had a tendency to stop when it feels like it until you jump then it continues again.
And working with FatalLag I mean FatalStrike ^^
