So I did a set up on Spectacle Island for the Solar Array. Got the array itself, have an observatory, advanced weapons, tech salvage, and circuitry lab. Got the solar panels aligned, got the micro transponder and linked it, got the encrypted schematics, decrypted them for the C-Finder schematics. CUE will not show up at advanced weapons. I tried refreshing the plot, rebuilding local data, updating to the newest version of SS, manually installing SS, refreshing and rebuilding again, nothing. Finally just finished trying to demolish and rebuild the advanced weapons plot from scratch, still nothing. One thing of note, I did build an advanced weapons plot in another settlement earlier, did the advanced weapons research quest there, but I checked that one and CUE not showing up there either.
