I own the Favorites Pack of Minecraft: Xbox One Edition, but none of my DLC will transfer over. To recap, I own the Battle and Beasts 1 and 2 skin packs, the Festive Mash-Up pack, the Halo mash-up pack, the Natural Texture Pack, the City Texture Pack, and the Fantasy Texture Pack (Everything that comes in the Favorites Pack), but none of it will transfer over from the old version. This is weird because all of the DLC in the pack is avalible on the Bedrock Edition.
