My female sim can't interact with my other sim (bundle)

I just got the birthday bundle and I'm playing Sims 1 and I find out that  one of my sims (female) de can't interact with my other sim (male) - but the male sim can actually interact with the female sim. I have my game installed in Swedish but when I click on the male sim (with the female sim selected) it says "Can't be used". The female can interact with everything else though, just not the other sim in the household.

The cheat "move_objects on" also doesn't seem to work because I can't do the restore motives trick with it.

The game also closes down if I save when a sim goes to work and when started again it's at a previous save and not the sim goes to work now-save point.

I don't know how to solve this. I want my Sims to be able to interact with each other.
