Thanks for your feedbacks!
We did fix a bug that piles of flax disappear, though.
Unfortunately, the same things happen on feathers. We'ill fix it.
And there is an approach to command survivors to throw away whatever they hold ---- press F9 and select the survivor.
In addition, it seems weird that I remembered to see some suggestions in your post, since busy then and did not leave a reply. But the suggestions just disappear!
