I'm trying to start this mod, but I can't find any of the items in the creative menu or JEI, the mod has controls in the controls menu but nothing else, I tried doing /give aswell but it doesn't do anything.

Mod Version 3.0.3
Minecraft Version: MultiMC 1.12.2

1.12.2 is usually unsupported but....logs...?

Found the issue, guess when I installed it onto my server it stopped in the middle of the installation and didn't add the full mod, reinstalling fixed it.
