It's still a bit buggy, i find myself having to reverse undergrounds and back again because they stop working and that fixes it, and belts that stop working when you rotate a belt piece and i have to pick up and put down the controller back again. Also sometimes, depending on the order in which you place down a belt, belts after / before a curve don't get powered. I also find it annoying that splitters / undergrounds interrupt the electricity flow, meaning if you have some fancy splitters you need a ton of controllers and you can't just use your regular blueprints etc.
I really like the idea and kudos for making this mod, but there are still too many issues for it to be really enjoyable atm.
