OK, here I am registered.
Mine villagers are watering that dammed field, but there was no harvest for over 24 hours! If that is a bug, then a deadly one. Now I have to cheat with the editor to have some food. One of my villagers died during the night from starvation and some more of them are in red already (I gave them not enough food for the night).
Until I research enough points to buy harvest level 3 for fishing, I will have to cheat to survive. Strange...
