This is something I've never had happen before, and I've searched around for the answer, but can't find that anyone else has had it happen either. I'm playing a Legacy family, and oldest son of the 2nd generation is -- "handicapped". He can't walk on any slopes. When he transitioned to a child, I noticed that he missed school, but I didn't know why. The next day was the same. He started to go to the bus, but he couldn't cross the arched bridge. I had to move him with
moveobjects on back and forth across the bridge every day to get him to school and back. No other sim had a problem with the bridge, as I had a thriving home business with sims on the bridge all day long. I finally had to flatten the bridge completely for him before he could use it. He can't go into the walk-in basement, either. There are a few other areas on the lot that are slightly sloped, and he will get stuck there too. He won't go around the other way unless I direct him around manually. He's a teen now, and he still has the same problems.
Has anyone else seen this happen? I thought it was an interesting problem, at least.
