If this issue is related to compatibility with other mods, such as missing recipes, make sure to follow these steps before reporting
I've been forced to experiment a bit with 1.21.1, and i noticed that jade forcefully auto-disables its mod ID tooltips if this is installed (i can't stand it when mod devs do this without letting you disable it, and it seems like this mod is the one disabling it - but i can't disable EMI's system and have jade's take it over. Would be nice if that was fixed).
So far, i've only noticed it in create's mechanical crafting tab (screenshot attached) - but it's possible other mods are affected.
