I find it quite annoying that you can’t use Gunpowder in Schematicannons when using Destroy. Would you consider readding it as fuel? I think Schematicannons shouldn’t be that hard to use. And also the SchematicannonInventoryMixin even has a comment saying

This allows any Destroy explosive (not just gunpowder)

Fixed in 0.6.

When is it coming out and is there a workaround for now?
