Many thanks; I’ve been interpreting that concept completely wrong, then. I was thinking that given the 2MPs to go from to Level 0 to Level 1 of a Building, that equated to a 2nd hex of “distance.”
Although now thinking about it in the context of you correcting my misinterpretation, I guess it wouldn‘t make sense that a unit on the ground outside a building could be “adjacent” to another unit in the upper level of that same building and still be two hexes away. That would affect executing the Threat 1 and Threat 2 orders in the Solo Assistant as well, I now realize.
