Uninvited guest in City Living

Last night a townie walked into my sim's penthouse apartment saying "... I'm really enjoying access to your place..." and I couldn't get rid of him. Didn't get the "Send Home" option when I clicked on him, closest I could find was "Go Away" but that just made him walk several meters away. When he jumped into my pool I thought I had him dead after putting up a fence around it but the guys just treaded water forever though frequently complaining about being tired and hungry. Eventually I just pulled him into the family so I could just delete him, though his Hunger and Energy need was bottomed off in the red he just wouldn't drown. Did notice he had the Goofball trait.

So is uninvited "guests" a "feature" of City Living? If it's some part of apartment living we should have some sort of interaction like "Leave through the door or I'll throw you out the window". Locked the door to everyone but my sim, which will be a pain if he ever wants to invite others over. Wish I could have used MCCC but it seems to be causing issues and had to disable it.

Yea, I wasn't happy.
