Sims getting confused

Hi,

I recently bought the Sims 4 and expansions on Xbox One. I've been playing a few days now and one of my households is getting very confused with the Clean Up option.

Having searched online, I have replaced the microwave, dishwasher, oven and fridge, all the waste bins and all to no avail.

It's not that they won't clean up, the problem is that they seem to think there's a bin in a place that there isn't. I click on clean up, and they go upstairs and put the plates on a table. If I click again they put them in the dishwasher downstairs. These are dirty plates that need scraping off into the bin and placing them on the table seems to do that in my poor confused Sims' minds. I deleted the table and they started putting the plates on the floor upstairs. I added more bins in that room, but they ignore them and keep using the floor. The bins are all empty, so that's not the problem. I have two dishwashers they can access, and this happens when neither are in use. The same thing happens if I try clicking on the dishwasher and choosing load dishwasher.

Any ideas on anything else I can try? I don't want to delete the household so if this can't be fixed, I guess I'll just have to drag everything into the bin manually, but I'd rather that it worked as intended.

Many thanks

Traci
