Suggestion: Rename the "Oak Savanna" biome to "Quercine Savanna", to make the mod feel more linguistically rich.

Quercine (Quer-"sine" or Quer-"seen") - "relating to oak trees"

It might be difficult to rename the biome registry name (what shows up in the F3 dialog and in /locatebiome) without breaking existing worlds, until Forge adds a good DataFixerUpper API, but you could modify the display name. Shouldn't be too bad to have it named the two slightly different things.

Places I've found where it's defined:

• twilightforest/src/main/resources/data/twilightforest/patchouli_books/guide/en_us/entries/world/biomes/general_biomes.json

  Line 49 in 7403322

  "title": "Oak Savannah",

  (no other language entries - can also remove the 'h' if nothing else)
• The language files here: https://github.com/TeamTwilight/twilightforest/tree/1.16.x/src/main/resources/assets/twilightforest/lang (All biome names in English, and only the set in en_us.json seems to be uncommented)

Unfortunately, this is not a change we're looking to make. We're happy with the current naming scheme, and oak savannas are a real life thing.

oak savannas are a real life thing.

Oh, cool to know. That does change my view a bit!
