Please note that spigot 1.13.x is no longer supported. It's time to update at least to 1.14.x - 1.16.x
New features require new implementations (newer spigot versions; 1.14.x - 1.16.x). To provide stability and maintainability, 1.13 is not supported in future versions. Thank you for your understanding
3.2.2
ADDED
- LECTERN to default protect-able list
- Lecterns can be opened by everyone, but the book can only be taken by trusted players
