Minecraft Halloween mashup pack

Hello! Over the years, with the "Happier Together" update, the Halloween 2015 mix set has been broken.In the Minecraft market, it is shown that the sky should be orange, the water is purple, but the sky is vanilla, the water too, it spoils the atmosphere of the map, also, some interface textures were broken. Please fix this, many players paid $5 for cheating, and many players have already reported this misunderstanding, but they were ignored.
