Waterflask can be created with Hardened Leather

[gorza]

The waterflask can be created with hardened leather even if there is the normal leather in the inventory.

Steps to reproduce:
1) Put both types of leather to the inventory
2) Craft a waterflask [Craft -> Tools]
Result: the hardened leather will be used for crafting, not the normal one as expected

Hardened leather is currently able to be used in any leather recipe, including making another hardened leather... be careful

Edit: Oh, and the crafting will use whatever material has been placed last into inventory... so if you place the hardened, then the regular, it will use the regular.
