I can reproduce the error every time.
Cutting some branches. Splitting them into thirds.
First thing that goes wrong: If I choose "sharpen a stick" the game creates 5 sharpend sticks instead of one. If I choose "sharpen all stick" it creates allso the five, what is to be expected in this case.
If I drag a stack of 5 feathers on to this stack of five, it creates 5 arrows, but uses only one of the feathers. If I drag one feather on a single sharpened stick, it also creates five arrows .. wow.
Could be nice, but if I drag the stack of five arrows onto my bow, the bow is only loaded with one arrow. And the "magazin" is not shown as mentioned.
In any case I'm not able to load the bow with 5 arrows.
