Rose Petal Resource Pack = Ice World?

I purchased the Rose Petal Resource Pack by 4KS Studios intending to build a lovely Victorian style house but what I got instead of a rich, warm world with palm trees like in the pictures was an ice world frozen over. I ran for quite a while but never saw a different biome. If that's what they created, then they should advertise it properly. Otherwise, it seems like it is not loading correctly.
