[4.1.0] - Unreleased

Added

• Other mods can now put real Treasure2 chests in their own structures. Until now the only way was to build a Treasure2 chest block into the structure file itself and run Treasure2's chest processor over it — which makes Treasure2 a hard requirement, and leaves that structure broken for anyone playing without it. A mod can now keep a marker of its own and ask Treasure2 for a chest while its structure is being built, so Treasure2 can stay an optional companion instead of a dependency.
• A chest placed that way is a real one, not an imitation. Its rarity, which chest it is, its locks, its loot and any mimic are all chosen by Treasure2 exactly as they are for Treasure2's own structures, and it is recorded the same way, so everything that keeps track of chests knows it is there. A mod can also ask for a particular rarity — a boss room, say — or name the loot table itself, and the rest of the chest is still Treasure2's to decide. Asking for a specific rarity deliberately does not disturb the rarity balance for chests generated normally.

Changed

• The chest processor's loot_table setting now does something. It could always be written into a processor list, and was quietly ignored — a pack that set it got whatever loot table the chest's rarity would have given anyway, with nothing to say the line had no effect. None of Treasure2's own files set it, so no chest generated by Treasure2 changes; a datapack that did set it will now get the loot table it asked for.
• The chest processor's alt_loot_table setting now works as a fallback. If no loot table can be found for a chest's rarity when it's first opened, the chest is filled from that table instead of staying sealed and empty. It was silently ignored before. Treasure2's ruins, wells, dungeons and surface chests set it: vanilla dungeon loot, or a handful of coins.
• On a server, a modified client could make poison and wither mist hit any player it liked, wherever they were. Mist now only ever affects the player actually standing in it.
• A chest could open completely empty and stay that way if its loot couldn't be generated the first time it was opened. It now stays sealed and tries again the next time it's opened, instead of being emptied for good.
• Breaking or blowing up a mimic chest no longer defuses it. The mimic springs, just as if the chest had been opened, so a locked mimic can no longer be picked up and carried off as a chest.
• Clients are no longer told which chests are mimics, so a mod or NBT viewer can't give them away.
• Key rings and pouches no longer lose their custom name, enchantments or other mods' data on the client.
• Update notices work again. Since 4.0.4 the mod had been checking the wrong update file, so no new version was ever announced in game.
• Treasure2 now loads after GottschCore, the library it depends on. It had been set to load before it.
• A mimic no longer makes its ambient sound while it is still dormant. It goes quiet until it is sprung from a chest or finds a target.
• The big teeth of crate and moldy crate mimics no longer poke up through the lid while the mimic opens.
• The Viking chest mimic's teeth no longer poke through its lid.
• Lock pick tooltips now show the chances set in the config, the same ones used when picking a lock. They showed made-up chances before, so the Pilferer's Lock Pick claimed 24% on uncommon locks when the real chance is 32%, and on a server they could show 0%.
• Callandor can now be found. Its place in the mythical loot pool handed out Oathbringer instead, so Callandor never dropped.
• Better gear is now enchanted better. Rare diamond armor came unenchanted while Rare iron armor was heavily enchanted, Epic iron armor was enchanted more than Epic diamond armor, and the Rare and Scarce diamond swords were weaker than the iron ones. Diamond now always comes enchanted at least as well as iron.
• The Epic iron sword no longer stacks three rounds of enchanting.
• The Nether Star no longer turns up in Rare chests, where it was more likely than a diamond block. It now starts at Epic.
• Harmful potions in loot are now splash potions: Weakness, Poison, Harming and Treasure2's Extra Strong Poison. As drinkable potions they only ever hurt whoever drank them.
• Common chests no longer hold a useless Mundane Potion; it's a Healing potion now. The Regeneration potion in Common chests turns up five times as often (it was 1 in 31).

[4.0.6] - 2026-09-06

Changed

• Fixed a dedicated server crash on startup when installed alongside Equipment Standards Overhaul (ESO). The eye patch armor material was missing its material name on the server side, which caused datapack loading to fail before the world could load.

[4.0.5] - 2026-08-13

Changed

• Structures and chests were noticeably rarer when playing with Biomes O' Plenty. Several BOP biomes were never registered as valid generation biomes, so any terrain they covered was quietly skipped. Bayou, Bog, Marsh, Fungal Jungle and Overgrown Greens now generate treasure like their vanilla counterparts.
• Forest and jungle wishing wells never appeared in Biomes O' Plenty forests or jungles. They now do.
• Biomes We've Gone jungles were being offered forest wishing wells instead of jungle wishing wells. They now get jungle wells.

[4.0.4] - 2026-07-19

Changed

• Locked chests could sometimes open up completely empty, even though they clearly had a lock on them. Loot generation is now much more reliable, so a locked chest should always have something inside.
• Chests found underwater (shipwrecks, sunken ruins) were quietly using the same rarity and loot rules as chests found on land. They now use their own underwater rules, so what you find down there should feel more distinct from land loot.
