I accidentally crafted A taste of the new world without checking my inventory, and found I had accidentally used both of my flints, and neither of my plain 'stones' While I think that in itself is a minor bug, this one is slightly different. After my first error, when I was making more I opened my inventory. I removed one of the two flints because it was highlighted green showing the craft would use it, and dropped it. Then, even though I had two simple stones in my inventory it would not highlight one of those. This is filed under trivial because I simply had to close the crafting menu and reopen it in order for the problem to resolve itself, but I figured I should post here anyway.
