Weird Travel Glitch

I tried the other night to travel with a few of the family, and when I got to Egypt, this is what I saw.
With no simmies listed, nothing in the wish or attribute boxes. Just nothing.
Good reminder to save before and after events!!
So I tried it again, same thing. And again, same thing.
I was afraid I'd have to dump this family or stop traveling with them at least (and I am working on a Relic Hunter LTW!)
I checked on my non-traveling simmies, just looking around to see if I can figure out what's going on, and then I found this:

One of my teens was stuck on a part of the architecture that is on the outside of the house on the third floor. I have no idea how she got out there. I assuming that she being stuck is the reason my traveling wasn't going right.
Luckily, I used the 'moveobjects on' cheat, and put her back in the house, and she was fine. (that cheat has not always helped my stuck simmies)
How in the world did she just happen to get out there I wonder?!?
