Houses won't evolve

[Former user]

The houses won't evolve past Small hovel despite access to markets and food. Says the dwellers supply their own food from the countryside and the stocks in the markets don't decrease. Market workers walk as expected and pass the houses. Running on OS X 10.9.5.

I'm having an issue with the latest update on Steam where houses won't evolve. The save game is from an older version, but they are all stuck with "this house will soon evolve" but they never do.
