### Fixed

- **Reload:** Config reload failures now log the config file path and full cause (e.g. invalid JSON, codec error) so you can fix the file and retry `/ha reload`.

- **Reload:** When one config fails to load, only that config is kept; other configs still reload. Managers are only reloaded when their config loads successfully (e.g. disabling title and reloading no longer leaves titles running if title config had been broken).

- **Blank lines:** Empty or whitespace-only lines in join/leave messages and in chat announcements are no longer sent, preventing stray blank lines in chat.

- **Join/leave title:** Primary and secondary title lines are taken from the first and second non-blank lines; blank lines no longer produce empty titles.

### Changed

- **Documentation:** Troubleshooting now includes "Default Hytale Leave Message Still Appears" (API limitation) and expanded "Configuration Not Reloading" with log path/cause and per-config reload behavior.

- **Code:** Comment in leave handler updated for future `setBroadcastLeaveMessage` use if Hytale adds it.
