Changes from the builds on which the Official Strategy Guide is based and the final retail version now have been confirmed to include the following:
1. Raw fish no longer is available at the Fish Shop. Pascal sells only 'grilled' fish;
2. Decent Cocoons no longer can be purchased from the Brownie Ranch. This does not negate the exploitation I discovered but makes it a little more difficult as you must have silkworms of your own to spin the Cocoons. There still is profit to be made using your own Cocoons by transforming them into Silk Thread, then using Blue Herb to dye them to create the product with the highest shipping value.
3. From what I have been told, Wool no longer can be purchased from the Brownie Ranch either.
