When I first started playing entrenchment, the TEC starbase would rotate so that it could bring the maximum number of weapons to bear against it's primary target.  Then, one of the updates seemed to remove this feature - I figured it was a balance fix.  Recently, the latest update seems to allow the starbase to rotate again - but only sometimes.  Is there a reason why it would work sometimes and not others?  Is it a bug?  Maybe it rotates against "easy" players but not "hard" ai?
