Stackable logs and ores

[Sargent]

This is only really true if pickaxes/hatchets do not break, which they do (and they cost some gil). So they usually go home whenever all their pickaxes/hatchets break, not really when their inventory is full. Look at harvesting, stuff from that do stack and sickles breaks less often, and it's not hurting the economy any.

Not to mention if you could carry 12 times more ores/logs, you'd need 12 times more hachets etc to mine/log them (roughly speaking).
