'Ghost' Blueprint not showing
Hadn't played for a while and decided to come back but now when I go to place a blueprint only a small section of the left most wall or a corner shows as I'm placing, so I have no idea where the rest of the building is until I try to place it. It gives me this error.

I realised what the issue was pretty much immediately after posting this, not sure how to delete the discussion?

(It was the windows btw)

I'm suffering from the same issue and have no clue on it, can you briefly explain your solution?

Welp, I found out myself. Its due to some mod furniture or structure causing error(rendering error I assume). For me its a door arc from the 'Gloomy Furniture' Mod (or Ratkin?), anyway you get my idea.
Do a quick test by drag blueprints over the furniture you suspect(probably especially those overlays above), if the error was thrown, then dismantle it then you should be able to create a blueprint.

My error log as below:
