My sims are obsessed with wall speakers.

I am not sure this will fix the problem or not. What wall speaker are you using? They have different fun ratings. One called Cafe is meant for public venues. (the debug one) Anyway, I think it was the outdoor one that has a high fun rating. It is a Sim magnate. I noticed the fun rating was higher. I stick with the base game one I think. I don't have my game open so I can't look. Also, if you see your Sims getting Eco points from dancing it is a N.A.P. making them dance. I turned them off but my Sims still get points with anything to do with gardening. In my game NAPS still pass and go into effect even when the Eco stuff is turned off. Another thing to fix I guess. The game generated the green gardening one and that's when my garden started reverting back to just planted.
