Well, I play sins a lot, and I personally like placing my buildings, but for some reason, it won't let me.  When I click on a building, it just auto-places it for me, and won't let me pick a spot for it.  This kind of bugs me.  I have looked through the options, and all I found for Autoplacing was the "Auto-Place Extractors" box, there was no Auto place period button.  Am I missing something blatantly obvious?  I have tried restarting the game, and all that.  It still doesn't work...
