you need to remove the overtime mod

The underlying problem here is that sims do not get enough fiber in their diet. What kind of effect would you expect a lifetime of eating nothing but waffles and fried ice cream to have?

But seriously what "overtime" mod would this be, then? I doubt we are talking about Buzzler's Moar Interactions mod as I've never heard of this issue before, could be mistaken. But is there another one?

Just get them the cheapest toilet possible; mine break it roughly every day, I suspect it's the only reason they even use it
