Description

Attempts to simulate traditional string duper functionality in 1.21.2+ since it was patched. Please report any bugs on the issue tracker.

Also contains config options to modify the minimum and maximum amount one piece of string can drop when duped. By default, min: 1, max: 3.

Tested on: Spigot, Paper, Purpur, Folia, Fabric

It is not limited to these! It should work on any server software with one of these as an ancestor. Fabric versions work exactly like traditional string dupers, meaning they are still directional and must be sheared.

This mod is server-side, meaning the client doesn't need it installed to work. (But it still works in singleplayer!)
