Both Logistical and Tactical structures placing themselves.

I was playing with some mates of mine and about an hour into the game every time I would try and build any kind of a structure around any of my planets it would automatically place them as soon as I clicked the button.  This would result in logistical structures clustered around the areas where enemies came in or when I just wanted to see what would happen I queued up ten missle batteries and they all clustered in more or less the exact same spot.  Has anyone else had a problem with this and/or know how to fix it?
