Hi Guys, I am requesting what I think should be a fairly simple mod. I've tried to do it myself but have no idea what I am doing, so I will leave it to someone else's more capable hands. All I am trying to do is reduce how much the electronics factory (I am making computers) makes my sim population sick. Well, actually I want to eliminate it entirely if at all possible. Any help would be much appreciated! Thanks.
