If the province your building located is yours , produced soldiers directly added to garrison.
In case it's not your territory, you have to talk to village manager so that you can take produced soldiers.
Someone don't like to invest any time on building own buildings whereas the others want sand box style building system.
So I added both already-merged house prefabs and raw house parts.
While in besieging, only guard towers and cannons will be shown for optimization.
Player constructed castle wall could be added later like defense game but not in early access state
