1.120.0 (but also before that)

Details

instead of explaining it I'll simply post my changes I did with my own kitchen sink mod in order to fix various issues of all kinda mods:

as a sidenote & clarification: the issue is happening with only EMI and CC in the instance - meaning it ain't a mod issue caused by another mod

    public void register(EmiRegistry registry) {
        registry.setDefaultComparison(ModRegistry.Items.TURTLE_NORMAL.get(), turtleComparison);
        registry.setDefaultComparison(ModRegistry.Items.TURTLE_ADVANCED.get(), turtleComparison);
        registry.setDefaultComparison(ModRegistry.Items.POCKET_COMPUTER_NORMAL.get(), pocketComparison);
        registry.setDefaultComparison(ModRegistry.Items.POCKET_COMPUTER_ADVANCED.get(), pocketComparison);

        for (var stack : RecipeModHelpers.getExtraStacks(Minecraft.getInstance().level.registryAccess())) {
            EmiStack emiStack = EmiStack.of(stack);

            boolean alreadyRegistered = EmiStackList.stacks.stream()
                    .anyMatch(s -> s.equals(emiStack));

            if (!alreadyRegistered) {
                registry.addEmiStack(emiStack);
            }
        }
    }
