One of the advantages of choosing to be a dragon in Dragons Survival is having a 3x3 crafting grid in your inventory. It would really help if the crafting grid worked with Crafting Tweaks.

Dragon Survival does not allow third party downloads, making it difficult to test in my development environment.

However, you can try to enable Crafting Tweaks debug mode using /craftingtweaks debug and drag a square around the crafting slots, it should spit out JSON in the console that can be used for a datapack to support the mod.
