Chitin milling, resultant chitin powder is weightless and crashes game.

[Secret-Cisco]

Describe the bug

If you mill regular or borosilicated chitin in a windmill the resulting chitin powder with have a count of 0 and crash the game if you try to pick it up and put it down. If you load the game after milling and before collecting the results you get the proper amount of chitin powder. If you take the 0 count powder out then save/load it will become 4 chitin powder no matter how many chunks had gone into the mill.

And the mill says there's 0 chitin chunks inside for every chunk you put it, volume seems right though.

Steps To Reproduce

1. Place windmill
2. Load 1 or more chunks of chitin into windmill, noting number
3. start mill
4. wait 6 hours

5a. remove product 6a. it's 0 count of chitin powder 7a. save & load game 8a. now it's 4 count of chitin powder

5b. save & load before removing chitin powder 6b. remove product 7b. it's the proper number of chitin powder

Expected behavior

It always being the right amount.

Screenshots

with 10 chunks milled, collected after save/load
