New thing that recently come up. Don't know if it's new town or patch but when I use the "Add to household" cheat. I get the Multi-selected portrait glitch.
Information posted
here. This time it's a new file just started - was adding homeless townies to the household and everything glitched out.
Update: This happens now no matter how I move people in and it doesn't matter what town I do it in.
Edit Again: Seems to only happen when you move in more than one person into your home. If you marry into another home, it doesn't happen.
