Version 0.9.6a
When I expand a farm field, the number of farmers is increased while I am working the new ground to prepare it.
However, when the field is finally ready for use, the # of farmers assigned and Max number of farmers for the field reverts to the previous value instead of being increased to represent the new field size.
For example, using a 5x5 plot, I have two farmers assigned and the maximum is 4. When I expand it to 5 x 10, 2 more farmers are assigned to work it, but when the new ground is finished and ready for use, I am still only assigned 2 farmers, with a max of 4. The farmers that were added to work the new ground to prepare it switch back to laborers.
