Skyblock One Block

I purchased the map One Block Skyblock off the marketplace for $1.99 and when trying to play it I encountered a bug where the gnomes are unable to be bought. I looked it up and it seems like this is a common issue, as nobody is able to purchase the gnomes at all. This is ridiculous considering the map is purchased directly through the Minecraft marketplace. Everybody who bought this map either deserves a refund or for the map to be fixed so it can be enjoyed as intended.
