This came up in an online game I was playing yesterday and I wasn't confident in what would happen...
I have the Pieceworker Occupation:
Whenever you receive wood, clay, reed, stone or grain on an action space, you can buy one more of the same good for 1 food...
as well as the Landing Net Minor Improvement:
Whenever you receive reed on an action space, you receive an additional 2 food...
Suppose I have no food in my supply and take the Reed action space. Can I use the additional 2 food gained with the Landing Net to buy an additional Reed with the Pieceworker?
