"Need joy source" for a colony without people

[asanbr]

I built a single person colony by sending a caravan next to my main, mostly to explore how it works.

The person got killed by 2 mad squirrels and no one is living there anymore.

I'm getting the "need joy source" message for this colony. The message is useless since it isn't true.

Update: same problem "need meal source"
