I am using 1.12.2 Minecraft and making a private pack. When i found Patchouli mod I've decided to make a little guide how to progress in this pack. I have created first category and entry but it is locked. I do not want to create mod only for advancements and I want to use for it standard Minecraft advancements. But I do not know how. I'm trying also to use Nuclearcraft's advancement "Nuclearcraft:root" but with no luck too. I have one more question: is there a hot reload for 1.12.2 version? I have tried to go to Discrord but the link is inactive.
