Can't fix ringworld?

[OrigamiPhoenix]

Got Cybrex.
Beelined for megaengineering.
"Cannot build in systems that have not been surveyed."
Even though I already have an outpost and full intel. Even tried dismantling the outpost and surprise, surprise: I've already surveyed the system!

Fuck me, man.

Update: I can't build ANY megastuctures. None. Hoorah.

I've seen this too. A temp fix is to to use the "survey" console command (if you don't mind seeing everything in the galaxy at this point in your game). Or you can edit the megastructure game files. For example, in 00_ring_world.txt, under "# Restored Ring World Segment", put a hash/comment symbol in the beginning of lines 357 to 366. This is what it will look like:

    possible = {
        from = { 
            has_technology = tech_mega_engineering
        }
#    custom_tooltip = {
#            fail_text = "requires_surveyed_system"
#            NOT = {
#                any_system_planet = {
#                    is_surveyed = {
#                        who = prev.from
#                        status = no
#                    }
#                }
#            }
        }
    }
