Shared Everything

🐛 Bug Fixes

• Game crash on startup — Fixed a second critical crash caused by the sleep mixin using CallbackInfoReturnable on a method that returns void. The mixin now correctly uses CallbackInfo.
• Sleep mechanic reworked — Instead of trying to override the return value of updateSleepingPlayers, all other players are now set to the sleeping position of the player who is actually in a bed. This makes the sleep counter reach 100% naturally, skipping the night without any crashes.

🐛 Bug Fixes

• Game crash on startup — Fixed a critical crash caused by the air sync mixin failing to find the setAir method due to Yarn mapping obfuscation. The mixin has been removed and replaced with a tick-based solution that works reliably.
• Air / bubble bar sync reworked — Air level is now synchronized directly in the tick loop using getAir() instead of intercepting setAir(). The player with the least air determines the value for everyone, ensuring a shared underwater experience without any crashes.

✨ New Features

• Air / bubble bar synced — Being underwater now shows the bubble bar for all players, not just the one who is submerged. Air level is kept in sync across everyone.
• One player can skip the night — Only one player needs to sleep in a bed to skip the night. The rest of the server does not have to sleep.
• Shared respawn point — When a player dies and respawns at their bed or respawn anchor, all other online players are teleported to that location as well.

🐛 Bug Fixes

• Item duplication when moving items simultaneously — Fixed a race condition where one player dropping an item while another player was quickly moving items in their inventory at the same time could result in duplicated stacks. A short settle timer (120ms) now ensures only one inventory state is used as the source of truth per sync cycle.

🐛 Bug Fixes

• Item duplication on drop — Fixed a bug where dropping a stack of items (e.g. 8 blocks) would leave behind a duplicated item that could be placed infinitely.
• Offhand duplication — Fixed items in the offhand duplicating or reappearing inconsistently when removed.
• Armor desync — Equipping armor now correctly syncs to all players, and removing a piece of armor no longer leaves duplicated copies in other players' armor slots.
• Armor durability not shared — Taking damage now correctly damages everyone's armor, not just the player who got hit. Armor durability is now fully synced across all players.
• Removed Ender Pearl teleport feature — The shared teleport-on-throw behavior has been removed per feedback.
• Milk not clearing effects — Drinking milk now properly removes all status effects from every player, not just the one who drank it.
• General inventory sync rework — Replaced the old event-based inventory sync with a tick-based diff system that compares each player's full inventory every sync cycle. This fixes a wide range of duplication and desync issues caused by the previous approach, including passive changes (like armor damage) that don't go through normal item-set events.

⚙️ Internal Changes

• Status effect sync now also removes effects that are no longer present on any player (not just adding new ones), fixing edge cases where effects would "stick" even after running out for everyone.
• Added loop-prevention safeguards across all sync systems to avoid duplicate or recursive sync calls.

• Offhand & item slots — Items no longer reappear after being removed from the offhand or any inventory slot. Fixed an infinite sync loop that was causing this behavior.
• Item stacks not growing — Breaking blocks no longer results in only 1 item staying in the inventory. Items now stack correctly across all players.
• Items could not be dropped — Players can now properly drop items. Previously dropped items would instantly reappear due to the sync loop.
• Respawn broken — Players who died were unable to respawn properly. Death and respawn now work correctly for all players.
• Screen shake on respawn — The screen no longer shakes/flickers after a player respawns.
• Health, hunger & XP not resetting on death — Stats now correctly carry over and sync after respawning, matching the other players' values.
• Golden apple hearts not shared — Absorption hearts (golden/enchanted apple) are now properly synced to all players.
• Effects not syncing — Status effects from potions, enchanted apples, beacons, etc. are now immediately shared with all players.
• Armor could not be unequipped — Players can now freely equip and unequip armor without it being forced back on.
• Enchantments disappearing — Enchantments on items are no longer lost during inventory sync. The mod now uses Minecraft 1.21.1's Data Component system for accurate item comparison and copying.
• Ender Pearl only teleported one player — Throwing an Ender Pearl now teleports all online players to the landing location.
