Trash will sometimes end up on the computer desk and there is no way to remove it. Even if you try to get one of your people to clean it up they just end up working on their career, playing online, etc...

That's not something that can be fixed. It seems to happen to some people when Virtual Families updates are installed over games already in progress. There is an event that can remove them, but, apart from that, there's nothing that can be done to correct it.

What event corrects that?
