The Useful Tools Mod

Fixed                                                                 

  - Spectral / Spectral-Infused armor mix-and-match — wearing a mix of native Spectral armor and ectoplasm-infused pieces now correctly hides the player from Ghosts. Previously the check was either-or (4 native or 4 infused), so any mixed loadout failed both branches and Ghosts could still see the player.
   (EctoplasmArmorHelper.isGhostInvisible)
  - Spectral-Infused armor tooltip — infused armor incorrectly showed "Can damage Ghosts". Armor doesn't damage Ghosts; tools/weapons do. Infused armor now reads "Hides you from Ghosts"; the damage line stays on tools and weapons. (new lang key tooltip.usefultoolsmod.ecto_armor_invisibility)              
  - Ghost spawn egg ignores config rate — using a Ghost Spawn Egg (or /summon, breeding, etc.) only succeeded ~15% of the time because ServerEntityEvents.ENTITY_LOAD was discarding any Ghost that failed Config.ghostSpawnChance, regardless of how it spawned. The rate gate has been moved into the           
  SpawnRestriction predicate (GhostEntity::checkGhostSpawnRules), which Minecraft only consults during natural spawning. Spawn eggs and commands now always succeed; the kill-switch (ghostEnabled = false) still discards on load. Matches the 1.20-Fabric behavior.                                             
  - Ghost spawn location restored to mid-air — SpawnRestriction was registered with SpawnLocationTypes.ON_GROUND, requiring solid blocks beneath spawn candidates. Ghosts fly with noGravity = true, so the 1.20-Fabric port used NO_RESTRICTIONS to allow floating spawns. Switched to                           
  SpawnLocationTypes.UNRESTRICTED (the 1.21.1 equivalent) so natural spawns can occur in open air again.                                                                                                                                                                                                                                                                                                 
  - Removed two orphan advancement files (rgold_from_blasting_rgold, rgold_from_smelting_rgold) that referenced non-existent recipes — leftovers from the original 1.20-Forge JSON migration.                                                                                                                     
  - Datagen completeness: ModBlockTagProvider and ModRecipeProvider were missing 14 block tags (3 needs_* + 11 incorrect_*) and the grenade/dynamite recipes. The static resources covered them at jar build time, but a fresh runDatagen would have lost them. Backfilled both providers.                        
  - Spectral / Infused armor tooltip clarity — both tooltips now lead with "Full Set:" and use the same DARK_GREEN styling as other full-set lines, making it obvious the ghost-hiding effect requires a complete 4-piece set (any mix of native Spectral and Spectral-Infused). Was: "Ghosts will avoid you" /   
  "Hides you from Ghosts" in plain gray.
