Honestly, it's not the end of the world. Not good, but not the end of the world. Keep backing up, though, and make sure you have everyone extracted. It COULD be a sign of impending doom, but if it's isolated, it's probably not super impending. I've had child LTWs on and off since gen 2, and I've spotted some wants to talk to dogs, but my hood hasn't imploded yet, so I'm not freaking out.

However, I don't know anyone who's done a playing-more-than-just-the-main-house legacy who HASN'T had to do at least one rebuild, except for those who are only a couple of gens in. So having a new hood ready to go isn't a bad idea.

Also, yay old Matthew and Jan! Time for them to stop being stupid and get OUT. :P
