Making the game more accesible to new players.
This triggered the following idea. Start that mission (or a tutorial) with a similar setup. A small fully functional village that gets burned, but is used as a blueprint for the future village. (You will build a forester on the previous forester place, sawmill on the previous sawmill etc.)
This can be easily achieved with obstacles that lets you build only in that spot.
Just my 2 Cents...
