Trading Post return after attack

-zone has both: Trading Post and Marketplace
-pre-attack: 2/2 or 3/3 have been assigned to the Trading Post while 0/2 or 0/3 have been assigned to the Marketplace
-zone comes under attack
-workers that were assigned to the Trading Post auto-return to the Marketplace instead of the Trading Post they were assigned to - silently sabotaging reputation gain with the neutral faction they were assigned to the Trading Post for while also not showing as idle because they picked up the wrong task and remain busy with that one

Trading Post & Marketplace assigned workers should save information to which structure they were assigned, so that after an attack they'll attempt to return to work at that structure. This issue is only relevant to merchants and their Trading Post interaction.
