Traders stopped restocking wealth


As the title says all of the merchants I traded with stopped restocking their wealth. Some are stuck at 0, others at some low amount they were left with after my last trading with them. I’ve waited more than a week, tried spending a whole day/night cycle at the city without fast forwarding or sleeping, still nothing. I even tried a mod that is supposed to set their wealth to 20k, still nothing. The other merchants, that I don’t trade as often with, got their wealth set to 20k. This makes me wonder if this isn’t a bug?

P.S. I created a new topic since the only other one on this subject is old and nothing suggested there helped me.
