Added

• Litematica schematics (.litematic, ADR-058). Regions (schematic in definitions/regions/*.yml) and action PASTE_SCHEMATIC steps now accept .litematic files in schematics/ alongside .schem and .schematic, including multi-region Litematica files, negative region sizes and block entities. Config and action BIT checks accept .litematic paths as well.

Changed

• Action name collisions with /rtp, /wild or another action are now BIT errors (ACTADDON_NAME_COLLISION, ADR-121). /rtp test action-setup reports ACTADDON_NAME_COLLISION as an ERROR instead of a WARNING when an action's name or command alias collides with /rtp, /wild or another action, and names the existing owner in the message.

• /rtp reload reads and checks config files off the main thread. Full and single-section reloads (such as /rtp reload regions or /rtp reload worlds) now parse files and run config BIT checks asynchronously before swapping the active configuration on the main thread, and a reload started while another is already running replies with alreadyReloading instead of overlapping.

• /rtp config search expands multi-word queries and falls back to an online thesaurus. Multi-word searches strip punctuation before matching, and when local keys and the bundled thesaurus return no matches, /rtp config search queries an online synonym fallback off-thread.

• For addon developers. RTPPlayer adds default sendTitle(title, subtitle, fadeIn, stay, fadeOut) and sendActionbar(message) methods. In-session onStart and onBoundaryViolation action gates now pass the session's ActionContext to registered custom gate validators, and RTPRuntime.setServerAccessor keeps RTPAPI.serverAccessor in sync.

Fixed

• Background cache fill on NeoForge 1.21.1 could hang the server and trip the watchdog. The 1.21.1 chunk-ticket lookup bound the raw-level ticket method instead of the radius-based region-ticket method, turning a 0- or 1-chunk ticket radius into a 32-33 chunk generation radius around every loaded chunk, and temporary load tickets shared the rtp ticket type with kept-cache tickets. NeoForge 1.21.1 now binds the region-ticket method and uses a separate rtp_load ticket type with a 30-second expiry for temporary loads.

• Folia safety checks with safetyRadius > 0 could read loaded neighbor chunks off the region thread. When a candidate chunk's center was read from an offline region file while one of its safetyRadius neighbors was already loaded on the server, the neighbor check ran on the async worker instead of the owning region thread. Safety checks now hop to the region thread whenever any chunk in the safety square is loaded.

• Failed region economy checks left players stuck as "already teleporting", and rtp.free did not bypass balanceFloor. When a region's price or balanceFloor rejected a teleport, the player's incomplete teleport entry stayed active and blocked later /rtp commands with alreadyTeleporting. With toggleTargetPerms enabled, a target player who failed the economy check also did not refund the command sender. Economy and region checks now finish before a teleport session is recorded, rtp.free bypasses balanceFloor, and failed target charges refund the sender.

• Post-teleport title, subtitle, actionbar, consoleCommands and playerCommands did not run on Fabric or NeoForge, and toggling effectParsing ignored /rtp reload. Post-teleport titles, actionbars and commands now run on Fabric and NeoForge as well as Spigot, Paper and Folia (and are skipped for /rtp test mock players), and effectParsing in advanced/performance.yml updates on /rtp reload without a restart.

• Visual and sound effects on Folia could run off the player's region thread. Player-targeted effects now check region ownership on Folia and reschedule onto the player's entity scheduler when called from another thread.

• Bundled action definitions always loaded from the English locale folder. On startup and reload, the action addon read definitions/actions/ using "en" instead of the server's configured language in config.yml.

• Some translated keys in nested lang/<locale>/advanced/ files did not match their .lang.yml key maps, and /rtp docs messages hardcoded [RTP] instead of [P0]. Nested advanced/ locale files in de, it, pl, zh and cat now match their .lang.yml key-rename maps, and docsNotFound, docsEmpty, docsExportSuccess and docsExportFailed in advanced/messages/commands.yml now use the [P0] prefix placeholder across all locales.

• Unpacking an @config, @economy or @safety reference in /rtp editor could not be undone with Ctrl+Z. Unpacking a reference now records an undo/redo step, concurrent /rtp editor HTML exports no longer share a single temporary file, and unreachable relay servers log a single warning line without a stack trace when falling back to snapshot-only mode.

• The /rtp editor biome map on non-Anvil region formats used the .mca reader. Biome extraction for the web editor map now decodes chunks through the registered region-file reader for non-.mca formats instead of calling the Anvil .mca probe directly, and counts unreadable chunks in BIT status.

• World border startup checks skipped CIRCLE_DEPRECATED_PURE_SPIRAL and SQUARE_DEPRECATED_PURE_SPIRAL regions and string numbers. The world border check now recognizes both spiral shapes and numeric string values in region shape configs.

• Disconnecting players kept background-refill attribution history and could trigger warnings from open menus. Leaving the server now clears the player's autoTune refill attribution history, and chat or book menus and /rtp admin setup pages that finish rendering after the viewer disconnects skip the render without logging a warning stack trace.

• Concurrent bad-location flushes could fail with an array bounds error under heavy rejection load. Rebuilding a region's bad-location table while another worker recorded a rejected spot could overrun the snapshot buffer; the snapshot is now bounded to the allocated buffer size.

• Biome activity sampling could load unloaded player chunks on the main thread. Periodic biome sampling for players standing in or crossing into an unloaded chunk could trigger a synchronous chunk load on Bukkit and Paper; biome sampling now skips unloaded player chunks.
