Hello everyone. I would like to start off by saying Tech Tree Minami v3.1 is an awesome mod. It gives Rimworld that needed flavor of gameplay. Unfortunately I have hit a wall in production. It started when I tried to craft my first mechanical engine. I got my crafter to level 11 and I believe I have all the materials necessary to craft it. I set the que to build one and for the life of me my colonist won't build it. As a matter of fact, the only item he will craft on the MetalWorks bench is the light bulb. Am I missing something here?
