Versions
Mod: 3.11.1.390
Forge: 36.2.4
Minecraft: 1.16.5

This is not happening with the mod by itself or in Enigmatica 6 modpack that I play so I will need information from you on what other mod needs to be in pack for this to happen.

It's in my Netherium modpack: https://www.curseforge.com/minecraft/modpacks/netherium

There's like 150 mods, but I guess it could be Curio? Maybe Create? This wasn't an issue until recently though.

it's neither of those mods but I can see Equipment Compare in the mod dependencies so similar to the other ticket linked here you will need to report this bug there as their code conflicts with Forge's one.
