However, I can't get the centerpoint to be in the middle of the blueprint; it is always off by one, so that rotations break the alignment of the rail lines (and power too).
I can of course disable the grid snap, and manually place down the blueprints adjacent to each other so that everything connects, but the global grid alignment won't play nice.
Is there any way to jiggery-poke the system to make this work with rotation?
The blueprint has 4-way symmetry, so ideally rotation should leave the layout identical. It isn't as important for this one specifically, but T intersections and straights will need to be able to be safely rotated since I don't want to have to make a bunch of nearly-duplicate blueprints containing manually rotated versions.
I'm using Krastorio, but the blueprint includes only base-like rails, standard + chain signals and substations.
Blueprint is:
