I have 13 members living in one household, I want to send 3 to uni, it'll let me get as far as the moving screen, so I pick a uni and course and then it'll say split household and I click on the sim but it won't let me go no further...is there another mod I need to install to let me do this?
Ouch. I think you need to shift-click remove from household, then go to manage households and put them all into the same household there (they'll be "not in world"). I've never done it, so save first! maybe even save as first.
Edited to add: If you wanted to move them out with money, you should probably make a note of how much and manually cheat money into the new (uni student) household and out of the original household.
@GemzyX As you might know a 'normal' maximum number in a household is eight Sims. As soon as you use a mod to extend the number of Sims in your household the gam might cull members randomly. This can happen when you go to CAS or when you go to manage worlds. When you want to find a mod for the issue you are experiencing you could also check the creator of the mod that made it possible to have more than eight household members.
Have fun playing. 😉
I had this problem too - I assume it's because the base game only allows 8 Sims per household, and you need mods to increase that number (I use MCCC). What I ended up having to do in my 10-person household was go to household manager, split the family into two (I did 7 and 3, but 8 and 2 should work as well - just have to make it so that the households are 8 or under), and then you can send them to university. I put the Sims I wanted to send to university in a household temporarily (you can use freerealestateon if you don't plan on having them there long term and don't want to spend simoleons on this temporary fix), then use the computer to send them to university (this is assuming you want to move them into a dorm - I don't remember, but I think I couldn't get it to let me move them into a dorm from the manage worlds screen, I think I had to use the computer once they were already living in a private dwelling).
The downside is that once you do this, you might have to jump through some hoops if you want to move any of those Sims back into the original household if it would make the original household larger than 8. (Personally, my households usually only go over 8 through 'Try for Baby'/babies being born. I never bothered trying to do it any other way.)
