Under some circumstances, when all the marauding orcs belonging to the
horde operating within the gnomish mines had been provided with their
spoils and placed appropriately, there could still be some pillaged stuff
left-over on the migrating obj chain. Orcs created by regular monster
generation elsewhere would then be susceptable to receiving that stuff
until it was used up. That part is fine, except that the orcs were then
being named as part of the same horde operating within the mines. Now
they will no longer be named as part of the Gnomish Mines horde.

Mythos: There's a good chance that these particular orcs received the
stolen goods from the Gnomish Mines horde.
