Im using this mod with ftb monster, and whenever i hire someone to "maintain farm" they pull out a iron hoe and do absolutely nothing. Please help out wildmamboy. What am i doing wrong? (btw i can't take my gold out of their inventory)

1.6.4 is no longer supported. This is probably an old bug that was never noticed.

Correction, I just noticed what you meant: Maintain farm does just that, it maintains a farm in a certain area. They will not create new farms, they will simply wait until something is ready to be harvested, harvest it, and replant it.
