I feel as though I am communicating poorly. I was not asking for the blueprint to generate the new chunks, nor for it to work perfectly when the blueprint is placed in such a way as to extend into non-generated chunks. I was asking that, after the chunks have been generated, and explored, that the ...

I have attached a video of this happening.

In the video, you see that the construction bots are hovering over the area of rail blocked by the trees. No problem.

I pull out the blueprint, place it over the existing layout, and click. It tells me I can't build. There are trees in the way, so this is ...

The real bug here, though, is that, even after I have subsequently explored the area, and try placing a new copy of the blueprint, I cannot force it to deconstruct the trees and rocks. I would expect that, after the areas are explored, they would behave as they have every other time when I shift ...

Longer version:
I am working on making a grid-style layout for this factory, and, to simplify, I have blueprints for the rail layouts. These are twice the length of one of ...
