You make nice tower wars maps, but your maps have an annoying bug that you could avoid. Do not let the path end where you lose. The follow path script instruction contains a bug that can cause waves to move on a straight line from the very first path waypoint to the very last path waypoint. This can happen while they spawn and someone builds a structure on that straight line between the very first and very last waypoint. Let the path end so that there is no line between first and last waypoint on which a player could build a structure, for example, let the path end near where the path starts.
