If you want an industrial world to stay industrial "they" say I can't do it now without a mod. I had no luck with the mod. I have 5 industrial lots producing an industrial footprint and the neighborhood is still neutral. At this point you can mod the game or disable NAPS. If not "weird things" take place. I personally disabled the pack for now because my game would not run with the mod. It must conflict with another mod but I do not want to play without my main mods which are MCCC, UI Extension, Better Education and All Year plants. As of yesterday, because I decided to send two Sims to uni, I also have some mods that make things faster in the game. Faster Uni homework and faster song writing etc.
