Tried melting ice in flasks, heating the water directly instead of the skin, reviewing Blind’s tutorial to make sure I wasn’t doing it wrong, switched adventurers, tried a different world/character more than once before and after reinstalling the beta branch, reinstalled the beta branch, and none of these things worked. I did notice that I was unable to right click on the campfire and get the option to heat up the waterskin from doing that. Not sure if that’s related or not.

System is on Steam, OS is Windows 10, used easy as the option setting for the adventurer points.

* Note: Figured out a temporary (albeit cheesy) way of working around this bug. Dropping any quantity of water around the fire in the snow creates an infinite water glitch that allows me to retrieve water that I can put in my inventory.
