You won't. If you do you read an entry incorrectly in the book but you could trace back and figure out what you are off. We accidently placed a wood production sticker when we should have placed a market. We randomly replaced one wood with it and moved on.
There are exactly ten Captain's Booke entries that tell you to (for instance) mark a site as one that produces wood. Once you place your tenth wood-producing sticker, you can expect it won't ever ask you to do it again.
