I got the travel bug recently after the update was applied. Although I had saved it before going on vacation and I was just unable to go on vacation. I looked around the net and saw some suggestions but none of these worked.
I did get it fixed for my family in the end though. I noticed that the issue appeared to be with my vacation home, when I tried to travel to Egypt it took me to the vacation home but I had no family member there. I tried China (which I hadn't visited and my family loaded fine). So after trying to sell my vacation home in Egypt and visiting again (which didn't work...it still took me straight to the old vacation home with no family on load) I then went into the saves and renamed my 2 Egypt files to a .old extension. I tried visiting Egypt again and my family loaded absolutely fine, albeit without the vacation home or any tombs saved.
Perhaps the same will work for you, my family didn't lose the visa levels or anything. Just the vacation home and Egypt progress...no biggy.
