"Note that Tucker will only take up to four stacks of Rolanberries per trade and will only trade with you a total of three times. This means that to get the stack of Vellum you will need to trade him four stacks of Rolanberries three times."

This has always been a known thing - as he has a max times he trades to get your items. I don't believe this is a bug as it has always been this way unless they look to simplify this.
