One suggestion might be to wait a full second or so before you spawn the bot. That way the player will more than likely not be shooting and having recoil from the kill. Then place the bot for a full second or two and see if that gets hit.
Just an idea.
But the logic behind the plugin is to catch the players string of fire as he is killing an enemy. He will more than likely already moved on and released his shoot button after a second.
