I've been playing around with this mod for awhile and even after 20 new worlds (with a default config file) and my worlds only generate ice-type biomes

Here's a list of my efforts to change this:

• BiomeMode: Normal or FromImage
• Trying specific seeds
• Reverting back to v4.0 config files
• Exploring worlds for other biomes thoroughly
  Note I can find a few islands with green mountain biomes

FINALLY
I've since manually deleted all ice biome types from the config files and upon rendering a new world, I only get small, sandy islands.

Edit It seems there is a possibility for other biomes to render, but they only do so on small islands surrounded by ocean.

Not a bug, looks like user error. Discussion continued on the subreddit here:
