Hopefully EA will include this with their next patch....

My simmies went to France for the first time since installing LN. It's a fairly new neighborhood so one simmy is Visa 1 and her new hubby is Visa 0. They don't have the Jetsetter option so they are limited to 3 days travel. After 2 days and nights I decided to check the travel bar to see how much time they had left and discovered that the time hadn't advanced AT ALL!!!! I ended up having to manually send them home.

Has anyone else had this issue? It isn't game-threatening (LOL) but still curious if there is a fix for it!

Thx!

I've never ever had that, neither before nor after LN, and almost all of my Sims are dedicated travellers, with level 3 visa and vacation homes all over the world. So, I don't think that this is a common or repeatable issue. I did read, however, about other people having this issue occasionally.
The thing is, travelling with an unmodded game can be quite risky from time to time because of the whole exporting/importing that happens while World Adventures loads. Inventories can get lost, Sims can disappear, family trees can break, someone even claimed that their Sim had a sex change upon arrival. Except for the latter I experienced all of these from time to time in the past but since AwesomeMod and twallan's mods now fix most of them they haven't happened anymore. (Well, once I had the disappearing Sim again, but I think I know what I did wrong and was able to fix it)
As a general rule, I always save before I start to call the travel agent and then start a different save after my Sims have arrived. If anything goes wrong I discard that travel save and rather start my vacation again. You never know what bugs this may carry back with you into your main neighbourhood otherwise.

I have just developed this problem as well. I do not have LN. Traveling also does not satisfy wishes. I am still hunting for an answer.
