Alright, I saw a thread with the same exact problem as I'm having, but it's severely outdated and I didn't see any responses including a solution, so I'm making another.

I have all three expansion packs installed, and as far as I am aware, the most recent patch installed. Although I am running Sims on my laptop, it has always worked fine save for when my laptop would overheat. I'm led to assume that my issue is an easily fixable bug.

When my Sims travel to any location (any Sims at all) they do not show up. This has been happening for a few months, so I just stopped traveling, but what's the point of even having WA if not to travel?

Is there any reason this is happening? The only thing I have that might interfere would be a lighting hack, but that's relatively recent. This has been happening prior to me installing any CC and/or lighting hack.
