it isnt working for my single player minecraft server, does it only work for singleplayer worlds?

[ttyyyyyyyyyyyyytt]

tried to use it and it kept saying no seeds, i looked at a tutural but idk what to do

not really a solution to ur problem but client commands (mod) also by earthcomputer has a much better implementation of enchantment cracking and automates a lot of the processes i really recommend using that mod
