This one took a while for me to pin down becuase the first
1-3 trips I didn't think to actually do a comparison of before and after- however..
When I shipped the 4th trade writ- I took stock, got evidence, snipped some stuff and compared before & after and noticed that the amount that was 'paid out' was 1535.. which was far lower than everyone else told me. (In hindsight this was just noise), but this resulted in the new stealth update where the actual payouts are announced to the player when they turn trade goods in.
However I got 2 new trade writs today- and performed the writ functions- and now have data to compare against and can now say for certain that trade writs are not paying out correctly- I've done 5 small 250 writs and one large 500 writ, and there now exists a nearl 80,000 cloth discrepancy that exists between what the stockpile should be- and what it is at currently, I.. don't know how this is happening or why to be honest- just that it is happening and the differences now between what the stockpile should be at and what it is at is.. now kinda absurd- and thats just me doing it, who knows what other players have been doing trade writs for Sibayad or other towns have been doing!
