I'm so sorry, it turns out I messed up the item reductions for the crafting (basically, the game hasn't been displaying the actual number of items that you still have but a number that you would have had if you never crafted anything) I fixed it now so that it actually displays the real number. I think you might be missing 3 vines, since 13 vines are used for crafting the spear and the ladder and you need 10 for the last craftable. The rest should be good though!
