I sent one of my Sims to a Getaway and wanted to leave him there for a week to focus on the other sims in the household.
I just recently did this, and now every time I open my household lot I see a Sim (another Sim, not mine) that should be in the Getaway hanging around indefinitely in my household instead. It's impossible to ask them to leave. I know they are one of the Getaway ones because their role in the Getaway appear under their name.
I went back to to Getaway and back to my household and this just changed which of the Getaway Sims was in my household, but there was still one there. The first time, it was one of the Visitors; now, it's one of the Entertainers.
[Edit] As soon as I canceled the Getaway my household lot was reloaded and the random Getaway Sim was not there anymore.
[Edit] I don't use any mods or CC.
