Using spacebar, I alligned the camera so that I was looking through the orb of a tower - it is a see-through ball of light, but if you look at units through this ball, all you see are the shadows of the units and not their actual models. A small thing yes, but it should be fixed, if only to rid of the 'well that doesn't make sense, how come I can only see their shadows through this orb?' clause.
Ps The orbs look AMAZING close-up by the way!
