I have the latest version of the mod and I'm using it in the Farming Valley modpack. The blacksmith worked before I updated the mod but now he just says generic chat lines and doesn't even offer the shop hours option anymore.

*Edit: Church is also having this issue.

Replace the script you have with this script and it should fix

There is nothing I can do about how a modpack alters stuff, so closing this now.
Very kind of @spykid01 to provide a solution though :)
