For context, I see this occurring in my logs with a handful of mods, each often with slightly differing errors. I am using version 1.21.11 of Fabric.
Every time the game is started up, this error is thrown without fail:
[17:31:46] [Render thread/ERROR]: Couldn't load creativecore pack metadata: Pack declares support for format 50, but game versions supporting formats 17 to 64 require a supported_formats field. Add "supported_formats": [50, 64] or require a version greater or equal to 65.0.
It's not really an issue and doesn't appear to functionally affect gameplay in any capacity (as it should, given this is just a core mod), but it's a bit odd to appear nonetheless.
