Can't Pour or Create a Flask

Thirst is low, in desperation…

I have the items to create a Flask as listed in the Wiki:
1 Clay Blowpipe (It’s not Raw, I used a Kiln to craft it)
2 Refined Sand
1 Lit Furnace
But it does not appear in the crafts…

A little later I created a Solar Still Huzzah!
Except I don’t know how to use it. I poured water on it. Then nothing happened. I figured it needed more water so I went to the ocean and tried. The Solar Still is already full…

I figure I have to manually fill my waterskin from it. But the waterskin is currently full with unpurified water. I need to dump it out…
I tried at the ocean, it just drops the waterskin.
If I had been standing at deep water I would have thrown away my waterskin…
I tried to douse the lit Kiln & Furnace in my house.
“You cannot drop or use An unpurified Filled waterskin here!”
So I lit a tree on fire…
“You cannot drop or use An unpurified Filled waterskin here!”
The burning tree is now spreading and burning my home…
This is nuts…
I can’t pour out water?
What if I needed an empty waterskin to craft…
or Drink? Actually I need a drink… bad.

Hoping for a fix, till then I’ll just sit in my burning home and stare at the tools in my hands that are supposed to create a Flask. I could make another waterskin, but I need some leather, I’m already dehydrated now so I’ll wait rather then risk going out and hunting for some.
