The rooftop locator upgrade requires a folding chair to create, but in Experimental 2024-01-03-0320 (the version I'm using for testing Milestone 1), it appears that the folding chair only spawns in convention centers and cannot be crafted. The common outdoor chair is instead the camp chair, which I assume is what the recipe is theoretically meant to be asking for even if the crafting menu doesn't currently accept it as a suitable replacement.
