I'm updating a resource pack and planning to test it in 1.13, the soon-to-be-current release version. I've updated my pack.mcmeta to reflect the current version (4), and have appropriately renamed everything according to 'The Flattening'. However, when I load up the snapshot of my choice (18w22b) to test, activating the resource pack leads to all black and purple i.e. none of the textures are recognized. I suspect there is something fundamentally wrong with pack.mcmeta so I'm showing it here for feedback on at least that much. If there are any other potential problems that can cause this please help me out! I'm trying to get back on track with this pack— I've been working off and on on it for about 3 years now.
