Add a custom helper function here, so that heroes with a blink/travel, declare this above:
function behaviorLib.CustomMoveToRuneExecute(botBrain, rune.location)
	return false
end

And on this line:
if not behaviorLib.CustomMoveToRuneExecute(botBrain, rune.location) then
  return behaviorLib.MoveExecute(botBrain, rune.location)
end
