I currently have the 1.12 version of minecraft and forge as well as the mods. None of the mods crash, and when clicking on mods in the menu or in game menu they all show up. However actually using the mods doesn't work. The mods are all open source and none are my own. Why don't they work and what do I need to do to fix them so they do work?

What I mean is that none of the associated commands work. Wand doesn't work. It's basically standard commands you would normally find without mods. Although one does work which is the journeymap. Aside from that one worldedit cui, biomes o plenty, jei, and waystones don't work.

A list of commands I would normally use but aren't functioning are as follow:

//cut

//paste

//paste -a

//copy

//rotate

//pos1 and pos2

//flip 

/butcher

Can't make selections with the wand either.

I was able to find an updated worldedit and cui file.

WorldEdit CUI Forge Edition 2-2.1.1-mf-1.12-14.21.0.2334 and

worldedit-bukkit-6.1.7.2

I understand those commands aren't standard and only come from worldedit which is why they don't work and standard commands like /time and /weather do work.
