In Minecraft switch edition I bought the norse mythology pack soon after its release. Fast forward to this summer I download bedrock edition and start to transfer my norse castle world over. Of course I download the mashup pack again, but when the textures swap on the menu as usual, the missing textures colors (pink and black checker board) appear instead. Included in this bug, the world does not load, but stays at the loading screen. Once I did get the world to load but it was the regular texture pack, not the norse pack. I'm highly disappointed, and I hope to see this bug resolved, preferably soon.
