Watt Bots asks about delivering Building Units, and whether they have to have the gray side down. No, none of the Missions require the Building Units to be oriented any particular way, except for Flat Down on the mat, or Flat Down on lower Stack levels.
In fact, if you look at the pictures that illustrate scoring for Mission 12, you can see Building Units in a variety of orientations.

Question... When delivering building units, do they have to be right-side up? Or does it count if they are gray-side up? Our team is debating...
Thanks for clarification/verification,
