notnotmelon's fork of Factorissimo 2 has a feature where copying one of the buildings themselves copies everything inside. I think it's copying too literally though, as it's letting me dupe high level buildings despite not having taken apart any.
Is this something patchable on this end or is this an issue to bring up over there? (Assuming notnotmelon can leave a response, they haven't updated their mod in 9 months.)
Edit: There also might be an Issue with nanobots: Early bots
It's kinda hard to figure out. the blueprint appearing in Factorissimo buildings have a level number despite normal blueprinting not doing that.
And Nanobots will either place normal assemblers or ones with levels.
