I logged in today and the only things I can build now when I push "B" or manually go to the crafting menu is the hunting knife augmentation, the refined cooking station and the simple cooking station. When the menu pops open for a second I can see everything and it goes away. I tried logging out and back in. I have things soooo many things unlocked in my inventory
I had to just create a new character because the building never came back to her.
