Minecolonies version

Version: currently 0.10.138-ALPHA but problem occured several versions before

Expected behavior

A Farmer should work on all assigned fields

Actual behaviour

The farmer only works on the latest built field. Sometimes he walks to the seccond last built farm and harvests about 1 pumpkin per hour. The field he harvests is planted with wheat. The seccond is pumkin and the third is carrots.

Farmer level is 17, hut-level is 5
hire+fire had no effect. Recall and Restart also had no effect.

Serverrestart also had no effect.

Steps to reproduce the problem

Exactly same issue at least trough last 10 alpha builds too. Have to do all work for them.
Farmer is only tending one field, even if assigned to 2 or 3.
