The Teal Socks recipe is currently bugged within the Crafting tab:
-Displays as a duplicate of the Yellow Socks recipe by name, when used/added to your recipe list
-Requires Teal Yarn, but makes Yellow Socks
(It's properly labelled as Teal in the Mole Market, and I believe in the Crafting tab before it's used as well. I didn't check if it displays the right name in the inventory)
