Don’t know whether it should be like this or not. But the vills just do one sheep/harvest one bush until they start idle.
for example: Build a house, shift+click a vill to go-to food (berries/sheep) again. after the sheep or berry bush is empty, they start to idle for no reason because they are enough bushes/sheep around. It does not happen on wood. They cut down one tree after another.
Furthermore sometimes the vills idle but it needs some time until the notification goes on for this. But the vills are standing around for 5-10 seconds.
Thanks for listening!
Stay healthy.
