Discover university room mate system broken?

@AlHollandiyahyes and no, depending on if you want to keep the Maxis Sims! 😉 You can go ahead and play with them along your Sim for an extra challenge, but if you don't want them as playable Sims you can move them out of the dorm! 🙂  

There are supposed to be 2 ways to do this but I can only get one of them to work.

What worked for me was to move your Sim in with the Maxis Sim or Sims (I saved my game right away) and then immediately go to the Manage Worlds button on the top right of the screen (looks like a grid with a location marker).  Then you should get the box asking if you want to manage worlds or save and manage worlds.  Click on either of those and you should be brought to the Britechester map.  From the map, click on the dorm where your Sim (and the Sim or Sims you can control right now) are living. Just click to highlight the dorm.  Then in the bottom right of your screen click on the button called More that looks like 3 dots.  This will bring up 3 more buttons and from here you want to click on the button that is called Manage Households (looks like 2 persons and a pencil on it). Then you should see your Sim and the Maxis Sim(s) on the left and some buttons on the right.  Click on the button with arrows going in right and left called Transfer Sims.  Then you will see another bigger box with your Sims and the other(s) on the left and a big blank space on the right.  At the top of the blank space is a long button that says Create New Household -- click on that .  Then choose the Sim or Sims you don't want to live in the dorm anymore.  In the case of the Best Friends household, you would click on both of them and their pictures will turn green at the edges.  Then click the arrow pointing to the right and the Maxis Sims you don't want will go in the blank box with yours still in the box on the left.  (If you want you can put the Maxis Sims in another household also, but I just made a new household that wasn't in the world. )  With the Maxis Sims in the right box and yours in the left you can click the check mark in the bottom right of the box.  Another box will probably pop up to confirm your decision. 🙂
From there you can re-enter the dorm. The Maxis Sims will be located at the dorm, but they will be visitors and you can't control them anymore because they are no longer in your household! 🙌

The other way that I couldn't get to work was to have the Maxis Sims move out by having them do so by phone (you can have them drop out of university if you want).  I tried to do this with one of the Best Friends, and she split from the household and a loading screen popped up (I assume so you could move her into a new home, and then I planned on doing this with the other Best Friend and then returning to the dorm to play my Sim)… but when the loading screen popped up it just loaded for more than 5 minutes which never happens in my game.😞  I tried it twice but it happened both times. This is either a glitch in just my game, or a bug in everyone's game.🤔  (I don't play with Mods or CC!).  

Now, about adding your own additional Sims to one of yours that is already in the dorm, I cannot get it to work!  I do not know if I'm going about it wrong or if it is a bug that might be fixed later, or if this was what the developers intended. 🤔  I will have to research this a bit more and get back to you! 🤨

You are welcome to try the 2nd method, but since I didn't get that to work I can only recommend the 1st method!🤨
If you have anymore questions, please feel free to ask! And please update on how this works for you! 😇 Happy Simming! 🥳
