The blue unit is the key here, although the terminology isn't totally correct. "Independent" has a special meaning from Rule 33, which means "not touching any [team] equipment]. There's no team equipment in the third picture, so that's not an issue. For people who think that there are 7 levels from the white/tan/blue units, note that the blue unit does not form a stack 1 level high. To be considered a Stack, a collection of building units must have Level 1 touching Flat Down on the Mat, and the blue unit isn't touching the Mat. A Stack also has any higher levels touching Flat Down on the level below. In the third picture, the blue unit is touching Flat Down on both the Level 3 Tan and White units. The blue unit is Level 4 whether you travel up the white side, or travel up the tan side. Because it touches Flat Down on both, the whole collection of white/tan/blue is a single Stack of height 4. It does take a lot of staring and thinking to understand the Mission 12 scoring, so these are good questions.
