In the valley, the group tasks are identified by the yelling chicken (chicken with an exclamation mark). Could it be possible to identify the delivery tasks with a chicken holding a box? That way it would be easier to find them. Sometimes I spend all my fuel and haven’t found one. I do touch the different building to see the tasks, but often I can’t find them.

Also, put more group tasks is valley. Sometimes there are several group tasks at the same time. Then there’s none for days, making it impossible to do the group tasks.
