[Open] Sims is duplicated living in two houses

@allybally1115 could you try to move him again to a different lot?

@allybally1115 Have you tried moving your Sim to another lot as @Phantomlover1717 suggested?

Yes, I tried doing this. Still didn’t solve the problem. I’m going to just retire the sim after I complete his career. Not sure what else I can do.

There is an alternative way of solving this issue as @theurbanflair told us on their post a couple of days ago. Would you like to try this?

I had this same issue, contacted EA who tried to help me but the roll back on their servers didn't solve it.

I thought logically and knew in my mind that the playable sim who was showing as two Sims was obviously taking two slots, therefore the fourth playable sim was an extra ilegal fifth SIM.

I struggled through playing till the duplicate SIM retired along with the other three who were activated with him and guess what? All SIM slots became visible without the X in the aim slot box!! Only problem I had is the duplicate SIM who retired had a whole new life as a new playable sim, with a second chance at life, which I had no choice over!! But I still had three slot to create or make new playable ones. Hope this helps!!

The retired duplicate Sim returned as a regular playable sim, retired but Still playable, so i changed the grey hair to blonde and he is having more babies!! Maybe when he retires next time he will be gone. 

Please tell us if this works for you.
