TH Item Stages is a relatively new Game Stages alternative that is allows devs to hide items in JEI. I tried to enable this for Reliquary, but it appears that items will still be displayed. The disabling of a whole mod only requires its modid to be used, so I put in "reliquary", but items continued to appear. I'm either using the wrong modid (and would be delighted to learn the right one), or there's a fix from one of the mods to be made.

Could you point me to that mod? by you saying it's relatively new game stages alternative to Game Stages I don't suppose you mean https://www.curseforge.com/minecraft/mc-mods/item-stages which is Game Stages addon and was created 5 years ago.

I will need to understand what that mod does to know what may be wrong on my side.

Anything else you might need?

Sure, here's the mod I'm referring to: https://www.curseforge.com/minecraft/mc-mods/totally-harmonious-item-stages#:~:text=Totally%20Harmonious%20Item%20Stages%20(T.H.I.S.,is%20item%20gating%20behind%20stages.

This mod is able to create stages for items, dimensions, and blocks through config files. A particular feature of the mod is the ability is to hide items in JEI, something that Reliquary appears to not be compatible with.

And what version of Reliquary are you trying this with and what mod id have you put in config to hide the items?

I'm using reliquary-1.18.2-2.0.12.1143.jar, using "reliquary" as the mod id.
