Whenever my sim goes to the Flea Market, there are picnic benches covering the tarps where furniture should be sold (no, they are definitely not items for sale). Whenever my sim goes to GeekCon, there are picnic benches that seem to be left over from the Romance Festival blocking the entrance to some of the virtual reality games. During the Spice Festival, there are those cases you can play a guitar or violin on blocking one of the grills. Now when I say covering or blocking in the three previously mentioned examples, I also mean that these items "spawn into" whatever they are blocking, meaning they are "inside" of each other. I'm under the impression that the game doesn't "de-spawn" (make disappear) certain things in order to make room for the stuff that spawns during a festival.
Is this a known bug? Is there anything I can do to my game to fix it? I really like these festivals.
