Locks Reforged

[1.7.5] — NeoForge 1.21.1 — Forge Parity & Stability

This release brings the NeoForge 1.21.1 version in line with Forge 1.20.1 while fixing several port-specific issues.

Improved

• Ported the new server-secret lock combinations, legacy combination migration, and saved security data from Forge.
• Lockpicking now uses the same improved multiplayer validation, sequencing, and immediate final-pin unlocking as Forge.
• Structure-generated locks now receive independent combinations and preserve their state correctly.
• Improved Carry On recovery and optional adapter detection.
• Restored copper mechanism crafting when no common copper nugget tag is available.
• Improved worldgen, recipe, trade, and config reload behavior.
• Restored proper filtering for disabled enchantments in tables, loot, equipment, and librarian trades.

Fixed

• Fixed several key ring issues involving insertion, extraction, shift-clicking, malformed legacy keys, and saved data.
• Fixed older nested-stack migrations after chunk data upgrades.
• Fixed worldgen locks sometimes failing to register in already-loaded chunks.
• Fixed several client rendering issues involving lock animations, GUI drawing, HUD targets, and selection highlighting.
• Improved server/client state cleanup and SavedData handling.

Compatibility

• Version aligned with Forge 1.7.5.
• NeoForge network protocol increased to 5. Clients and servers must both update.
• Existing 1.7.5 combination security data is preserved.
• Downgrading to older NeoForge builds is not supported.
