After spending a couple of hours re-doing Riverview, i.e changing looks, clothes, redecorating houses and such, I find that my Sims are unable to visit other houses. When I click on their friends houses, there is simply no interaction available. Same thing on other houses. They can go to the clubs and stores but not houses. This happened yesterday. Today I started a new neighborhood and at first it worked fine. I noticed halfway through my makeover that the visiting problem had happened again. I cleared the caches and exited, then restarted the game. Now, all of the neighborhoods have the same problem--no visiting available.

Apparently the problem fixed itself. This morning everything was working. Go figure this stupid buggy game.
