Not getting money from selling?

Summary:
Not getting gold for selling

Steps to reproduce:
Unsure, I played for a long time and got gold properly, but when this trader arrived I tried to sell things and this error message popped up. I think I was selling cook’s spoons or mean beds at the time. In addition, this error appeared when I was selling to a survivalist merchant.

Expected Results:
Goods exchanged, money obtained.

Actual Results:
Goods exchanged, no money obtained.

Notes:
I’ll test selling beds again at the next merchant and see if I can sell beds or spoons to him.
