I did not initially realize that the upgrades are different from the "main quest" and was wondering why all my upgrades required parts that I could not produce. Not sure if it could be clearer than having the thing I was missing smack-dab in the middle of the screen, but just sharing some experience.
There's some overlap between the upgrade and the "main quest" shapes (often main quest shapes enter upgrade recipes, as not to be immediately useless as the objective is reached). The current objective is always displayed on the left of the screen (and you can pin additional recipes there if you want).
