Thanks to GlassBricks for the epic, legendary quality mod.

I am just learning to use, and I would like to take the Nefrums/Derek MacIntyre beginner base and essentially separate it in half to turn it into a mini-mega base for achievement hunting in SA.

How do I copy and paste large sections of the blueprint that is in stages? Do I have to move each stage with the first instance of an entity and manually line it up with the next one (i.e. moving like 15 stages and hope I dont mess it up)? Or am I just an idiot?

There's a "staged cut" and "staged copy" tool, available either via the quickbar (bottom right buttons) or keyboard shortcut, that might work for this purpose. It copies/cuts while preserving staging info.

And no, you're not an idiot, just the documentation is not up to date, lol. I'll try to update it soon.
