When the default config is generated it is unable to add powdered snow to the blocklist for the shovel.

The reason is you are trying to add minecraft:powdered_snow, the namespace ID for powdered snow is minecraft:powder_snow.

Along the same lines, you missed deepslate redstone ore on the default config.

Minor issue, we can just add powdered snow and the ore manually, but I wanted to let you know!

Thank you! Minor oversights on my part. Will adjust but won't publish a release for it as it's relatively minor.
