First i would like to say that this game is awesome. But I am not sure if it is a bug or i am just doing things wrong but when i make parts in the factory it does not use them. It is still importing the parts even if i have the station that makes the parts right next to the assembly station that requires the parts. I do have it connected to the resource conveyors. Also a suggestion i think would be nice is to have the ability to move the input and output doors. Maybe research for it if not right in the beginning. It would help with planning the layout of a factory.
