There is an exploit where I can just insert a negative amount when giving jobs, so I can get a lot of unemployed people and negative amounts in certain jobs. This allows me to get a lot of resources. However, this broke the game and the villagers stopped producing anything at all and just consumed resources only.
edit: playing this game normally is quite fun, though it is weird that a single builder can build so many houses and that you can get to negative resources without dying immediately.
