Is there any way to force the guards to stay at the guard towers? I have built towers specifically to guard against certain regions where blight hives tend to pop up and true enough, on occasion a hive queen will attack. This would be no big deal since I have placed the towers in that exact spot... except for the fact that the guards have a tendency to roam around the entire settlement. The autogun in the tower does a little damage but not enough by a long shot, and I'll be focusing on something else when suddenly the guard towers are razed to the ground by this monster because the stupid guards prefer to travel all around the colony instead of staying at their post.
