It seems using autosell will make people lose gold if you have an empty estate in your region.
Peasants Taxes 350 gold
Trade Balance + 200 gold
Collectable Tax Gold 550 gold
Estate of Size Peasants Tax Collected Knight Share Lord Share
Kihalin 40 % 5600 221 gold 2210gold
Wild Lands 60 % 8400 165 gold 165 gold
Region Totals 385 gold 0 gold 385 gold
Lord and Duke Shares
Lord Share 385 gold
Dukes Share - 20 gold
Lords Tax Income 365 gold
I highly doubt this was intended but by making the trade balanced added to the collectible tax, lords are actually losing gold unless you do not have any wild lands or empty estates as you lose a certain percentage of your gold when your collectible gold is distributed to wild lands/empty estates.
Without using the auto-sell offer, I should get 140 + 105 + 200 = 445 gold instead of 385 gold.
I'll have to think about a fix for this. The obvious solution is to apply the Wild Land bane before Trade Balance, but this may be working as intended...
