Traders not handing in gold after saved game

I was playing the ottomans and using the Sultanhani Trade Network with around 12 traders, all gold nodes were empty, so my only gold income came from the relics stored in the holy houses.
The market didnt work, the donkeys didn’t hand over gold, when clicking on them they also didn’t show hiw much gold they were carrying…
I made a normal market spawned some new traders, sent them to that market and still no changes.

I didn’t investigate it further if its a global civilzation thing, or only a ottoman’s issue…
Anyone can confirm?
thanks!
