Crafting menu does not take into account ANY items on the tile you are standing on.
For example, stand on your spare parts tile, and none of those components will be found for crafting. Stand on your tools tile and same thing.
Drop items for whatever recipe on the floor, stand on the tile, enter crafting menu and you will see all red (not available) components.
Any items on the tile you are standing on should be taken into account when crafting.
I know what the fix is for this, will get to it soon.
The issue is a bit different, tools on your tile can't be used to craft. I guess you can't use recipe you are standing on too but i don't have book on my current play.
