Reverting back to the old way and limiting the hiring 2 for harvesting and 2 for plowing at the max would be a better idea.
It is annoying when there are many people on a farm harvesting and plowing when it clearly isn't needed, that is when you get what i call "random harvesting or plowing". If people are rude enough to come right infront of me when there is plenty of crops, i just simply do the same back
We are very lucky here on Farmtown, the developers LISTEN to the players and respond quickly to our concerns unlike the developers of other games who don't give a c**p about the players and 9 times out of 10, ignore player feedback.
