🐛 Bug Fixes

Jail System

• Fixed jail escape via relogging — jailed players are now re-enforced on join (JailListener#onJoin → JailManager#restoreJailOnJoin): the enforcement cache is rebuilt on every join (even within the offline-cleanup window) and restoration also works without a database (the periodic cleanup keeps active jails in memory when no DB is configured). Previously the cache was cleared on quit and never restored, so a relog escaped the jail.
• Fixed jails not surviving server restarts — loadJailedPlayers() now runs in initializeDatabaseDependentComponents() after the (asynchronous) database is ready, instead of during onEnable when it was still null.
• /unjail now works for offline players — the database record is released even when the target is not online.
• Fixed jail enforcement being blocked by the plugin's own teleports — JailListener#onTeleport now exempts PLUGIN-cause teleports. Previously the plugin's own "teleport back into jail" (and, on Folia, the initial jailing teleport) was cancelled by the very teleport-prevention handler, so a jailed player could leave the jail radius and never be pulled back.
• Temporary jails now auto-release without a database — JailManager tracks an in-memory expiry as a fallback when no database is configured. With a database the UnbanScheduler remains the sole authority, so there is no duplicate handling or leaked entry.
• Fixed return-location being clobbered on re-jail — the pre-jail location is now saved with putIfAbsent, so restoring a jail (relog/restart) no longer overwrites the player's real return location with the jail spot.

Essentials Integration

• Essentials is now always preferred when hooked — when Essentials is present, jails are created and managed in Essentials; the built-in jail system is no longer used as a fallback in that case.
• Auto-creates an Essentials jail when none exists — if Essentials is hooked but no jail has been configured, BanHammer registers its configured jail location as an Essentials jail (via setJail) instead of falling back to the built-in system. An existing, admin-configured Essentials jail is preferred when present.
• Cell selection for /jail — new syntax /jail <player> <duration> [cell] [reason]. The optional cell targets a specific Essentials jail; when omitted, the configurable default cell is used. Tab-completion suggests existing cells, and a non-existent cell is rejected with the list of available ones. The hammer and reason-only commands use the default cell. Case-insensitive cell matching.
• /jail no longer requires a built-in jail location when Essentials is hooked — the location now comes from Essentials.

Messages

• Hammer feedback now renders MiniMessage — HammerListener deserializes MiniMessage tags (e.g. <green>…</green>) instead of sending them literally.

Configuration

• Resource pack is now disabled by default — resourcePack.enabled ships as false with empty url/hash (and Settings defaults to false). The texture pack is no longer bundled/sent by the plugin; host it yourself and opt in explicitly. Previously a freshly generated config re-enabled it with a hardcoded URL.
• New punishmentTypes.jail.useEssentials toggle — enable/disable the Essentials jail hook from the config (default true). When false, BanHammer always uses its built-in jail even if Essentials is installed. Applies on (re)start.
• New punishmentTypes.jail.essentia✨efaultJail (default "1") — the Essentials cell used by the hammer and by /jail when no cell is specified.

Punishments / IP Bans

• Fixed IP-ban removal with anonymization enabled — /unban no longer attempts to pardon an anonymized IP. The real IP is only pardoned when privacy.ipAnonymization: NONE; otherwise a hint to use the vanilla /pardon-ip is logged. Applied to both manual unban and the auto-unban scheduler.
• Muted players can no longer bypass chat blocking via namespaced commands (e.g. /minecraft:msg).

Presets

• Fixed memory leak — per-player preset selections are now cleared on quit.
• Thread-safety — preset lists are immutable snapshots swapped atomically on reload, preventing a possible ArithmeticException (modulo by zero) if a player cycled presets during /bh reload.
• Modernized sound resolution — new registry-based Sounds utility resolves both namespaced keys (block.note_block.pling) and legacy constants (BLOCK_NOTE_BLOCK_PLING).

Stability / Logging

• Removed noisy INFO-level debug logging from the jail, hammer-use, ban and Discord code paths (now debug).
• ModrinthUpdateChecker shared fields are now volatile for correct visibility between the async check and the main thread.
• GUIListener no longer risks a NullPointerException on inventory items without a display name.
