Getting married in game

Usually if you have your sim marry someone from another household, you will get a pop up to choose for them/other members of their household to move in with your sim.

I have the same problem - they were on a date, they wed, date ended, he left. No pop-up. I updated my game today.

Whoops, I couldn't get the search function to work before I replied, but now I found this, which is a manual solution: http://sims3.crinrict.com/en/2012/10/wedding-issues.html
