I am havingg this problem as well. I haven’t used MOO or CC/Mods. Above the counters though I have overhead cabinets but the really small size that you choose manually. This photo is from Carls Sims http://www.carls-sims-4-guide.com/gamepictures/building/tutorials/full-size/IMG-TS4-build_120.jpg
Im using the smaller one and the walls are medium sized so there’s a lot of space between the cabinets and the counter. Can this really be causing the problem? My other counters that are in the bathrooms work fine, it’s where my sims are going to prepare food when the counters in the kitchen aren’t working.
