Thats exactally what I did to get the dynamics in, make it in single player then when I was finished I switched it to multiplayer mode. I've only played one game with my brother and everything seemed to work great, and that was before the update. I didnt even seem to notice the bug with the elevator doors, I guess I wasnt paying attention. But it wouldnt bother me anyways, since it was just something I made for fun. I have to run for about 2 hours or so, but I'm willing to play when I get back if anyone is up for it. I'll post when I'm back
