Changelog

[1.2.0] - 2026-07-14

Added

• Alpha Zombies: rare enhanced zombies (2% spawn chance) with 60 HP, 1.5x scale, 5 attack damage, and angry villager particles
• Alpha Zombies drop: guaranteed loot bag + ender pearl + 3-5 XP bottles, 50% gold ingot, 10% diamond
• Baby Alpha Zombies can spawn (scaled to 1.5x baby size)
• Config subcategory for Alpha Zombies (5 settings)
• Ender pearls now drop from zombies (2% chance) — fixes End progression softlock

Fixed

• Pile-up no longer triggers on 1-block steps (requires 2+ block wall height)
• Pile-up gates on actual horizontalCollision instead of facing direction
• Pile-up requires 6 ticks of sustained blockage before triggering (no instant snap)
• Pile-up works in enclosed pits again (zombies with no path but an active target now trigger pile-up)
• NeoForge crash on launch: "Registry is already frozen"
• Cave spawning below Y=0 now works (fixed endY clamping to 1, replaced -1 sentinel with Integer.MIN_VALUE)
• Zombies no longer suffocate in 1-block gaps (added head clearance check)
• Nether ceiling is now dynamic instead of hardcoded 125
• Baby zombies no longer spawn when disabled (global mixin on finalizeSpawn, covers reinforcement spawns)

Changed

• Loot bag drop chance increased from 5% to 25%
• Sound markers at 25% strength when crouching
• Light tracking: 25% investigate chance (less aggressive)
• Sound pathfinding: 1/40 chance per tick (halved)
• Noisy zombies/leap: sneaking ignored if zombie has line of sight
• Wandering hordes: skip crouching players
• Pile-up cooldown widened to 10-20 ticks (was 4-10) — nearby zombies don't pop simultaneously
• Pile-up boost scales with wall height — bigger wall = bigger hop
• Applied Integer.MIN_VALUE sentinel to findGroundY, findSurfaceGroundY, and findCaveGroundY for consistency
• Removed redundant setBaby(false) from ZombieSpawnHandler (ZombieMixin handles it globally)

Config (new fields)

• alphaZombies, alphaSpawnChance, alphaHealth, alphaScale, alphaAttackDamage
