Alright, can someone please tell me how to make stuff actually work in the map builder? I build a core, click "Edit in game", plop down a drill, conveyor, and tower, and NONE of them work! not even sandbox only items! The item and liquid sources I can't be sure about (because conveyors don't work), but the power source generates NO power at all! I had a great Idea for a map but I can't build it if nothing works.
Edit: Alright I got it guys, thanks for the comments
