Please take a look at the shipping quota's for Ore in kingsmarch.

Here are what my ports are currently asking: Riben Fell: Crimson Iron 170,000 and Blue Zanthimum 12,0000 (finished the flowers but only have a bit over 5k bars of Iron so far from my maps (so 25k toward the shipment if I sent it now.); Ngakanu: Petrified Amber 84,000 and 46,000 Corn. (I have finished the corn but only have around 3.5 k bars of amber so 17.5 k toward the quota); Pondium: Bismuth 45,000 and 28,000 Wheat (wheat done and at around 3.5k bismuth bars so only 17.5 k toward that quota), Kalguur: Bismuth 69,000 and 17,000 Verisium (See above for amount of bismuth currenly have. currently have around 3k bars of verisium so 15k toward that quota), Te Onui: Crimson Iron 110,000, Petrified Amber 74,000, Pumpkins 17,000 (pumpkins done. above have listed my current stock on iron and amber)

I even sent an extra 50k Blue Zanthimum shipment to Riben Fell just to ship something. It feels like the ore parts of the quota's are way too high compared to the rate we get ore compared to the rate we can get the plants for trying to finish the quota challenges.
