Cobalt mirror

[Merlin69]

in the guide P it tells me to construct this in one of my inventory slots but when I do this there is no cobalt mirror in it to craft although I've got the necessary parts? Is this a bug?

Until you have the BP, you may need to purchase it. They are often sold at the small settlements by the Dude in the back that sells BP and conponents. If it part of a mission, you usually gain it before you need to build it. You may want to check your base computer and blueprint analyzer to see if it there.

Cobalt Mirror blueprint is not in the base computer nor analyzer.
You may find it only by grinding - looting the "eye" by solving a puzzle in Operation Centres and Manufacturing Facilities (signal booster - secure channels; to find those buildings) most times will drop a blueprint. Note that blueprint drop is random and lottery, you may collect all other possible ones and get numerous duplicates yet not receive cobalt mirror blueprint for years.
Thus I have to say +1 to suggestion of buying the item at any small settlement, rarely any doesn't sell it.

I got the blueprint from solving the puzzle and it's it my mission P system, I've got the necessary cobalt but still can't find it in the craft slots?
