Important Testing Note

⚠️ YOU MUST CREATE A NEW WORLD TO SEE DIAGON ALLEY!

• Structures only generate in newly-explored chunks
• Old worlds will NOT have Diagon Alley retroactively added
• Explore plains biomes in your new world to find it
• Or use /diagonalley locate (requires OP) to find the nearest one

Changed

• /diagonalley command - Now teleports directly to naturally generated mini-city (removed test platform subcommands)
• Ollivander spawn protection - Prevents multiple Ollivanders from spawning (checks 50-block radius)
• Balanced Wandmaker trades - Wands now cost appropriate emeralds:
  • Basic Wand: 16 emeralds (was 5)
  • Phoenix Wand: 32 emeralds (was 12)
  • Unicorn Wand: 28 emeralds (was 10)
  • Dragon Wand: 40 emeralds (was 15)
  • Master Wand: 50 emeralds (was 25)
  • Rare enchanted books: 64 emeralds (was 20)
• Limited trade restocks (1-3 per wand type instead of 8)
• Updated /diagonalley command with subcommands: teleport and locate
• Removed old broken wand shop structure system
• Structure generation now uses proper Minecraft worldgen system

Fixed

• Multiple Ollivanders spawning - Now checks for existing Ollivander within 100 blocks before spawning
• Overpowered wand trades - Balanced to reflect magical rarity (16-50 emeralds)
• Cramped building spacing - Buildings now properly spaced with ~25 blocks of open street between left/right sides
• Narrow street width - Increased from 12 to 50 blocks for proper WIDE city street (no longer narrow/cramped)
• Missing shop doors - All 8 shops now have functional doors matching their theme
• Structure generating in mountains/valleys - Now checks for flat terrain (±8 blocks max variation)
• Underground generation - Structure only generates at Y 60-90 on relatively flat ground

Known Limitations

• Mr. Ollivander uses default villager texture - Minecraft doesn't support custom villager skins without resource packs
  • He has a custom name: "§5Mr. Ollivander §7(Wandmaker)" with purple color
  • Uses Wandmaker profession (enchanting table workstation)
  • Has balanced trades for all wand types

Removed

• Old wand shop structure files (WandShopStructure, WandShopPiece)
• GenerateWandShopNBTCommand (no longer needed)
• Old wand_shop.json biome tag
• /locate wandshop command (replaced with /diagonalley locate)
• Test platform generation at (10000, 100, 10000) - /diagonalley now finds real structures only
