Changelog

Added

• Timed boss scheduler rules with per-row bossId, arenaId, spawn interval, and duplicate prevention while alive.
• Timed boss GUI controls for schedule rows and announcement settings.
• Timed announcement placeholders: $Boss, $Arena, $World.
• Boss wave random spawn controls: enable/disable random spawn locations and configurable random radius from boss origin.
• Boss level override support for RPGLeveling compatibility (0/blank = default behavior, >=1 = forced level).
• Expanded boss scaling support in advanced boss scaler UI, including movement speed scaling.
• Persistent state files for boss fights, timed spawns, and loot chest runtime state.

Changed

• Timed spawn despawn settings now override boss base timer when used.
• Timed despawn 0h 0m now means infinite lifetime (no forced despawn).
• Timed boss notifications default to 10-second display duration.
• Config startup now creates missing files and merges missing config keys on boot.

Fixed

• Boss event continuity over server restarts with retry-based link restoration for bosses/adds that load later.
• Crash path after /npc clean --confirm by guarding null world/location during queued loot handling.
• Timed event announcement reliability for server/world broadcast paths.
