Spawn is a great mod that adds mobs, but it have issues with mods that have recipes using vanilla sunflowers, since this mod adds own sunflower and remove vanilla sunflower generations.
This data pack partially fixes this issue by allowing vanilla sunflowers to be converted from spawn sunflowers. Vanilla sunflowers still do not appear in the creative inventory and may still cause issues with other mods that interact with sunflowers directly (e.g. Flowery Mooblooms).
