Randomized Block & Mob Drops

[2.0.4] — 2026-03-22 — Auto-Rebuild & Blacklist Fixes

🚀 New Features

• Auto-rebuild on mod or config change. Each world's datapack folder now stores an rbmd_config.txt file containing a hash of the active config and loaded mod list. On every world load, if the hash has changed (blacklist edited, toggle flipped, mod added/removed), the datapack is automatically rebuilt with the same seed. Drops stay the same for unchanged items — the cycle just updates to include or exclude new items.
• Mod list change detection. Adding or removing a mod automatically triggers a rebuild on next world load. No need to manually run /rbmdreshuffle.

🐛 Bug Fixes

• Fixed: mod blacklist not applying to existing worlds. The mod blacklist correctly excluded items from the in-memory permutation pool, but existing worlds reused the old datapack files on disk without regenerating — so blacklisted mod loot tables were still active. The new config hash system detects this and forces a rebuild.

⚙️ Technical / Internal

• buildConfigHash() hashes all config values plus the full mod list (mod ID + version) using a TreeSet for consistent ordering.
• Config hash stored in datapacks/rbmd_randomizer/rbmd_config.txt alongside the existing rbmd_seed.txt.
• Log line on rebuild: Config or mod list changed since last generation — rebuilding datapack.
