Hi, I went to the market to hire to plow for the first time.It took several tries Seams harder than it should have been.So whe the plower arived I such around to see how it would go.I could see every plot being plowed and coins being subtracted and esperiance being added.When the job was complete I went to help out friends.When I returned to plant,all the plots were not completed.I don't understand what went wrong with it.All plots had been plowed befor.How can I fixit now?And how can I be asured it will not happen again? Thank you, Crissy
