Once you have everything in chests it is little bit of a hassle to go the the Castle Inventory screen, scroll through it, or look for the chest that holds the items, to see if you still have them in stock or not for items you can not set a ‘Maintain rate’ for like wood and stone.
So a nice and helpful addition would be a Stock Keeper, same level requirements as Worker (none), that will alert you if you have run out of stone or wood ect, and or will also allow a ‘Maintain rate’ for those resources.
It could work like this:
-Without a Stock Keeper all trees and mine areas are chopped and mined as normal.
-With a Stock Keeper trees are chopped and stone/ect is mined until the ‘Maintain rate’ is reached and no other trees are chopped or mine areas are mined even when designated as ‘To harvest or Mine’. Workers will stop chopping and mining.
-An alert when running out of those items stocked and no (new) trees are or mine area is set to be harvested.
“Sir, we have run out of wood (or stone) and no trees or stone is set to be harvested”
But if when Ores are included Workers will still mine stone until they finally reach the desired Ore amount, producing (a lot of) byproducts from mining though to reach the ‘Maintain rate’ of that particular Ore.
A Stock Keeper would further have only the ‘Haul and Job’ setting and Job would be alerting and or assigning Workers and the player to Mine or Chop.
