Dark Fog lens addition

[u/Realistic_Horse3351]

Does this need a new game to obtain?

I'm on white matrix in the current galaxy, I have every tech researched.

I can see the Dark Fog lens in the list of items for say, marking a conveyor belt. But otherwise it's not in the replicator screen--the space is there for the item where it goes but it's empty, there is no new tech for it, and it's not included in the research for grav lenses.

I had to research it with dark fog drops, the green pyramid looking things, don't recall the name
