There is this round table in game that gets dirty but doesn't change texture to show that it's dirty. So my sim would sit and have lunch at that table and always complain that something stinks and I got her to vacuum her floors, moved the table, chairs, carpets thinking there must be something spoilt stuck there that I cannot see. I cleaned her inventory of all things spoilt, etc. it eventually dawned on me that maybe the table is dirty and sure thing, after getting her to clean it, it finally stopped stinking.
