Re: [Closed] Can’t move out sim upon retirement
This is not a bug. The dialogue box Household is full is a game feature introduced in February 2019 as mentioned in this EA Help article:
https://help.ea.com/en-us/help/the-sims/the-sims-mobile/aging-and-retirement-in-the-sims-mobile/
This is how retirement works now. Playable Sims become NPCs as they retire. When you have eight NPCs, the game will ask you to permanently remove one of them in order to make room for the Sim who is about to retire.
The advantage of having a retired Sim at home is the possibility of doing the career and hobby mentoring with them. After a couple of days the retired Sim will be able to move out.
The pop-up will also appear when you have a full household and try to add a new baby, or when you try to marry one of your playable Sims to a young NPC.
There is a bug report that covers other cases in which this pop-up should not appear. All of them involve marriage of playable Sims.
