What exactly means "Decaying Hamlet" at the actual Version?

[Kralith]

At the first day our town was a "Stable Hamlet".
Since the second day the status is "Decaying Hamlet".
The Upkeep is fine, we turned Rank 3 today.

I don't quite understand this status.
It seems nobody know for now, what it means and what to do against it.

But i think, Prometheus surely can explain.
