Not a huge deal, but not sure if the same bug continues through the rest of the tiers, so thought I'd bring it up now.
Crafting a rough hickory bow ends up with the same result whether you use hemp or linen strings. They should be named the same, but have different stats, which they don't.
The stat differences are listed
here. Right now the linen version is producing hemp stats. I haven't tried the silk yet.
