It seems the Commoner Vest doesn't exist for the sake of placing it in a stockpile, as in it's not even in an option in the list. I can make them, I just can't stockpile them, or select them to be destroyed. All other items from this mod work as intended however. I love the art of them, well done for a first mod.

I forgot to add one thing in the Vest's file. I fixed it and I think it works now. Now I just need to post the update. I hope that I will not mess something up
