Question on biome editing

[GCAT01]

First off, I have really been enjoying this map so far. Thank you for creating it!

I have been exploring the USA (where I'm from) and noticed the great plains are, well, missing. I have looked through your process (admittedly briefly) and was wondering if you could make a recommendation on how I could tweak the biomes to be a little more accurate. Could this be done in the map generation process or would I be better off using something like WorldEdit? Thank you!

This Earth Map is really outdated. I recommend using my new maps that can be found on Discord: https://discord.com/invite/jN85qkB3 or in this Google Spreadsheet: https://docs.google.com/spreadsheets/d/16Km0bkSAdUxtMCZQYn0q0Lbv24SsViV0K5gsTZQDoA8/edit#gid=0

The new maps have an updated biome placement and also got Plains in America.

I would totally do this, but I am using a set of mods for 1.12.2 so I need an older version of the map.

You can try to change the lines 318-346 in the world.js file.

replace this:
