I went to my neighbor's farm to sell several different items to one person only. I could only sell one item. I then had to reload the game to sell a 2nd crop. Then I had to reload to sell cow milk. What was working beautifully yesterday is totally screwed up today! And please note this took place after you did your changes today so the changes took effect!
And I'm replying here because you asked that we report if there was a problem with selling.
