hi @Jonny_K,
Okay I found the bug. Your shepherd has a perk for getting more resources out of an animal. Unfortunately, that extra resource is not owned by you, so you have to loot it.
In the next unstable release, you will own the wool automatically.
Thanks for reporting this.

Cool! I saw this too and wrongly assumed it was because I didn’t have enough haulers free. Is this also true for trappers? Same exact behavior for me there too.
