# Added * **Support for version 26.2** * **`/mirrormod debug` — verbose logging of the whole mirroring path with the reason a change was filtered out. Off by default; also available as debugLogging in the config.** * **`tntExplosionChunkRadius` (default 4) — radius, in chunks, for real vanilla explosions. Beyond it the crater is applied as block updates. -1 removes the limit.** * **`tntVisualChunkRadius` (default 8) — radius for the primed-TNT copies that show the ignition. -1 removes the limit.** * **The explosion summary in the log now reports the breakdown: how many chunks were covered by a real explosion, how many by the crater, and the crater size.**

### Fixed - TNT - **TNT now really explodes in every chunk.** The explosion result was never written back to the mirror template, so craters were filled straight back in — either by block tasks still sitting in the queue, or the next time the chunk reloaded. It looked exactly like "TNT didn't go off over here". The crater is now recorded in the template, so chunks that load later get it too. - **No more random repeat explosions.** Walking around after a detonation no longer sets off "spontaneous" blasts in freshly loaded chunks for the next 10 seconds. - **No more double explosions in one chunk.** Igniting TNT with a redstone torch mirrored the torch as well, and in every chunk that copy genuinely primed the mirrored TNT — on top of the mod's own scheduled wave. Result: craters twice as deep in some chunks. Mirror chunks no longer run TNT physics of their own. - **Fixed the lock-up where TNT refused to mirror at all.** After any mass explosion every loaded chunk was guarded for 10 seconds, and each failed attempt *extended* that guard — so it never expired as long as you kept trying. The guard is gone, replaced by three precise checks that can actually tell an echo from a player. ### Fixed — other - Craters and player-broken blocks survive a server restart. Air entries were being silently discarded when loading the saved template, so destruction was forgotten while construction was remembered. - Fluid flow watchers could stop ageing under load and hang around forever, holding a reference to the world. - Armor stand copies could be left behind when the removal budget was spent on unloaded chunks. - Player language data leaked on disconnect. - `/voidworld` could overwrite the owner of an existing world. - Several unbounded registries now have ceilings. ### Performance - Mirrored blocks no longer fire neighbour updates. Every copy used to wake six neighbours; across thousands of chunks that avalanche was the single biggest source of lag. - Loading a chunk no longer queues the entire template. Positions that already match are skipped outright, so a chunk that is already mirrored costs nothing. This was the main reason the server stuttered while you moved around. - Redstone polling was O(components × loaded chunks) and did a full cycle only every few dozen ticks. It is now O(components), so mirrored repeaters and comparators keep up. - Removed per-tick full-queue scans and a string allocation from the hottest loop. - Block budget raised from 10 ms to 12 ms per tick, total mod budget from 15 ms to 18 ms. ### Known limitations - The crater shape is sampled from one chunk, so on uneven terrain it is applied at the same local coordinates everywhere and can end up floating or buried. This is how the mod already handles breaking a natural block. - Each explosion adds roughly 150–250 template entries. Watch `/mirrormod status` and use `/mirrormod clear` if it gets heavy. - Mirrored mobs and armor stands in distant chunks do not tick — those chunks are loaded but not ticking. TNT is unaffected; its explosion is driven by server ticks.

* Fixed a bug where some chunks could contain "fragments" of your buildings. * Fixed: breaking a mirrored armor stand no longer leaves ghost copies in other mirrored chunks. * Cause: armor stand destruction skips the normal death event in vanilla, so the mod never caught it. Now tracked via entity removal instead.

* The armor rack is now correctly copied to other chunks (previously it was not mirrored at all). * Fixed crash when interacting with plates in some cases (outdated data could be applied to the wrong block). * Fixed server freeze when clicking on a record player in another chunk. * Fixed a bug that caused the record in some copies of the player to continue playing after stopping. * Fixed the disappearance of hostile mobs at night (copies of spawners no longer spawn mobs on their own and do not eat the mob limit). * Blown up TNT no longer "resurrects" active after re-entering the world. * TNT lit by a kresal explodes only in the chunk where it was set on fire — the other copies of TNT no longer disappear or explode with it. * Increased block copying performance in new chunks (slightly mitigates slowdowns on large builds). * The portal to the Lower World is now activated only in the chunk where it was lit (the frame is still copied, but the active portal itself is not). * The record inserted into the player is now synchronized to all player copies (including extraction).

* The long block spawn delay has been removed. * Fixed exponential multiplication of mobs — spawners in mirrored copies no longer generate endless waves of duplicates * The mod no longer forces the loading/generation of thousands of long—range chunks when installing or breaking a single block - lags and potential crashes/OOM on large buildings have been eliminated. * Fixed a double TNT explosion when ignited via redstone (torch, repeater, etc.) — previously, in some cases, two TNT exploded instead of one in reflected copies * /voidworld tp no longer teleports to the void without a floor if a world with that name has not yet been created via /voidworld create * Fixed a possible name collision in /voidworld create — two different world names can no longer randomly match at the same point. * Fixed memory leakage during long-term operation of the server with active redstone (pistons, observers, comparators, repeaters) * Mirroring now responds correctly to an axe, scissors, and flint and steel

* The first beta release of the Mirror mod! * Added real-time mirroring of blocks. * Fixed multiple block structures (doors, stairs, beds). * Optimized block queue and performance. * The long block spawn delay has been removed.
