This question already has an answer here:
I've played this game with 4 different characters that go up to level 85+ and i just ran into a unique problem.
When im in workshop mode in Sanctuary trying to build the molecular beam i only have one piece of the machine available to build. STABLIZED REFLECTOR PLATFORM. The other pieces simply aren't there in the special section. I have the artillery piece, robot workbench, and then the stablized reflector platform. That's all.
So weird and so frustrating.
I disabled all the mods and went back to the Glowing Sea mission and worked my way back to molecular level and the problem persists.
