[OPEN] Walls are Missing In Movers & Shakers (in Willow Creek )

I'm also having the missing walls issue. To answer the questions from Crinrict's first post, they seem to just be invisible. Sims still route through the doors and you can't place anything where the walls should be without moveobjects on. I also cannot delete the walls, and if I try to delete the whole room and rebuild, I still can't place walls or items where the walls should be. I have to bulldoze the lot entirely.
