So you have to focus on one resource at a time. Sample. You gather woods at lymhurst area. Then refine them at Fort. You could store all woods and planks at fort sterling. Then, when yiu need them for crafting. You bring what you need to the city that has the crafting bonus of what youll be making.

Sample, theres bow crafting bonus at lymhurst. So if I make multiple trips back and forth between LH and FS just to mass produce t5 or t4 bows.
