Issue description
Basically it's all in the title. Made a few blueprints on my main save including surfaces. Went to paste the blueprint as you normally do on a new save and the surfaces misalign in chunks, or chunks of the surface go missing when rotating the blueprint that includes them. Buildings rotate fine.
Reproduction steps
Create a blueprint that includes surfaces.
Load different save and rotate blueprint.
