Two very interesting savefiles. The borg with the ammy swapping was stuck in a loop because his inventory was too full. He was being given points for carrying the digger. As the borg was calculating the bonuses for trying on the new ammy, the digger was being over-written and this caused a false high reward. So he would swap. That was a very simple repair.
The town-scumming-non-attacking borg was being messed up due to his miscalculation of his fail-rate on Satisfy Hunger spell. Nice eh. That is the borg for you. The borg failed to flow to attack monsters because he thought his fail rate was too high on a particular spell.
