I have the latest version of pufferpush skills and pufferpush attributes on Minecraft 1.20.1 Forge and datapack installed but I get this error and the pufferpush skill tab shows "There doesn't seem to be anything here...".

If you are sure everything is installed correctly, then please send the game logs. You can alternatively try to install Default Skill Trees mod instead of a data pack.

not the original poster but I'm having a similar issue. it was working fine til a couple days ago, then suddenly the trees are all gone when I've made no changes to the files.

Debug log: https://pastebin.com/zAz8zTsZ
Latest log: https://pastebin.com/CnKxBctM

I noticed this stood out in the latest and debug logs:

[19Mar2025 19:13:29.391] [Render thread/INFO] [net.minecraft.server.level.progress.LoggerChunkProgressListener/]: Time elapsed: 921 ms
[19Mar2025 19:13:29.523] [Server thread/ERROR] [puffish_skills/]: [puffish_skills] Data pack `cyaneryth_mob_tree` could not be loaded:
Resource `cyaneryth_mob_tree:puffish_skills/categories/mining/category.json` does not exist
Resource `cyaneryth_mob_tree:puffish_skills/categories/mining/definitions.json` does not exist
Resource `cyaneryth_mob_tree:puffish_skills/categories/mining/skills.json` does not exist
Resource `cyaneryth_mob_tree:puffish_skills/categories/mining/connections.json` does not exist

and when I check config > puffish_skills the only file in there is config.json. I assume that's the directory being pointed to in that bit of the log but I'm not sure how those files could have gone missing.

edit: just tried installing a new instance of our pack but it doesn't have those missing files in the configs. where would those be stored?
