Leather output scales with creature size

So weird. If you aren't opposed to manually modding your game files like we had to before steam you can swap the skin template from my materials file for the one in the vanilla folder, and then swap my reactions for the vanilla ones in the same way.

Downgrading to 51.13 fixes the issue is the only valuable information I managed to gather

I tried on another laptop that has never had dwarf fortress downloaded before. I installed the game with steam cloud disabled, forwent DFHack, went to world gen, added the mod, and same error. I'm just gonna give up and assume I was never meant to have the leather fortress of my dreams. Thanks for at least attempting to help! I understand there is nothing you can do if you can't replicate it lol

Oh lol I don't know anything about how this works. I'm gonna try to experiment more today I guess

That's odd, then it probably didn't load my file and the reaction to butcher may not make skin gloves for the extra leather

Omg don't ask me why but removing the line "material_template_leather_broms" at the head of "material_template_leather_broms.txt" fixed it for me.

I wiped everything DF related and reinstalled DF then DFHack. Error persists. I uninstalled DFHack via the Steam uninstall button and tried again, the same error popping up. Maybe my computer is just specially fucked.

I'm using v5202. I can confirm installed_mods and mods directories are set up appropriately and the mod files exist nowhere else on my computer (even cleared steamapps\workshop\content\975370\). Error log entries are just "Duplicate Object: material_template SKIN_TEMPLATE" repeated per attempt to generate a world. It errors without any other mods loaded with the mod loaded at the bottom. I assume it must be DFHack then, but I'll reinstall the game and see if that fixes it now.

Not your fault... hopefully an uninstall/reinstall will be able to sort out the errors for the others. Have a good day/night!

Sorry about the inconvenience. I am glad you got it to work.
