When putting my custom tips in the game as a resource pack for my modpack, the Tips mod does see them within the game and correctly identifies them, but they are all shown as "disabled by the config" in the mod settings, and I don't see a way to "enable" them.

And also. while trying to disable the "stock" tips provided by the mod, I discovered that putting tips namespace into the list of blocked namespaces in the config does nothing, the default tips still show up in-game.

It turned out to be a syntax issue in the tip json files. Solved it.
