I love the Traveler mod, too, because it means I can actually Travel with my sims! For the longest time, I had no problems with traveling and then one day I came across the dreaded missing sim bug. I ended up abandoning that save, and I was pretty upset about that. Then I starting getting Traveling bugs far more frequently so I stopped Traveling all together.
Now I travel where ever and whenever I want. Such a great mod that people can use to play their game however they like.
