Stefan had just changed the farming system.
But, what he probably didn't think of, was the farming in the start.
I restarted, and i noticed that.
If you plant a corn, in the right way (even though the guy there says to do the old way

), the farmer waters it, but doesn't crop it. And you can't complete task three.
Also you can use unstick me in the mines... so if you have ell,a lot of iron by using the little buggys...
and you unstick there...
well, think for yourself

i used unstick there so i could go to the main island.
