This update changes some biome generation (Hence why it's v2.1.0 and not v2.0.3), but it shouldn't break existing worlds. Though i recommend to still backup your world!

• - Added some biomes like Forests, Birch Forests, Taigas, Mountains, etc. as possible biome spawns instead of plains.
• This has the effect of replacing some spots with said biomes where you otherwise would only get plains. So you no longer get plains that are 500x500 blocks big. It took me forever to figure out how to reduce the overabundance of plains, and adding non-plains biomes to the Climatic Biomes BiomeConfig for Plains was the only way where i actually spotted a difference.
• - Re-added Plains climate variants from Climatic Biomes (Cool Plains, Cold Plains, Windswept Plains & Cool Windswept Plains)
  - Added Sapphire ore generation to Glaciers (Can't believe i forgot that...)
  - Adjusted any sort of generation & spawns (That includes mob spawns, ore gen, stone gen, etc.) to accommodate the new changes in biome IDs
  - Increased time between each bat swarm attack from boss mobs from 10 to 15 seconds
  - Reduced bat health from the swarm attack from 10 hp per bat to 6hp per bat
  - Halfed XP level costs for reducing an items anvil repair cost by using a golden tool on it (Charm Feature)
