is it just my spaghetti code or is the mod bugging out
it is not adding the sequenced assembly recipes (how)

ServerEvents.recipes(e => {
	e.recipes.create.sequenced_assembly([
		'mekanism:basic_control_circuit'
	], 'mekanism:hdpe_sheet', [
		e.recipes.createDeploying('kubejs:inc_basic_circuit', ['kubejs:inc_basic_circuit', 'minecraft:slimeball']),			e.recipes.createDeploying('kubejs:inc_basic_circuit', ['kubejs:inc_basic_circuit', 'minecraft:redstone_dust']),
		e.recipes.createDeploying('kubejs:inc_basic_circuit', ['kubejs:inc_basic_circuit', 'minecraft:redstone_torch'])
	]).transitionalItem('kubejs:inc_basic_circuit').loops(5);

	e.recipes.create.sequenced_assembly(
		['mekanism:advanced_control_circuit'],'mekanism:hdpe_sheet',
		[e.recipes.createDeploying('kubejs:inc_advanced_circuit',['kubejs:inc_advanced_circuit','mekanism:basic_control_circuit']),
                e.recipes.createDeploying('kubejs:inc_advanced_circuit',['kubejs:inc_advanced_circuit','mekanism:infused_alloy']),
                e.recipes.createDeploying('kubejs:inc_advanced_circuit',['kubejs:inc_advanced_circuit','minecraft:redstone_dust']),
                e.recipes.createDeploying('kubejs:inc_advanced_circuit',['kubejs:inc_advanced_circuit','create:electron_tube']),
                e.recipes.createDeploying('kubejs:inc_advanced_circuit',['kubejs:inc_advanced_circuit','#forge:wires/copper']),
                ]
	).transitionalItem('kubejs:inc_advanced_circuit');

})

both of the recipes aren't added

Please fix it, I'm creating a modpack

I swear I have added the transitional items
Proof:

StartupEvents.registry('item', e => {
  // The texture for this item has to be placed in kubejs/assets/kubejs/textures/item/test_item.png
  e.create('inc_basic_circuit', 'create:sequenced_assembly').displayName("Incomplete Basic Circuit");
  e.create('inc_advanced_circuit', 'create:sequenced_assembly').displayName("Incomplete Advanced Circuit");
  e.create('inc_elite_circuit', 'create:sequenced_assembly').displayName("Incomplete Elite Circuit");
  e.create('inc_ultimate_circuit', 'create:sequenced_assembly').displayName("Incomplete Ultimate Circuit");
  e.create('pcb_press', 'create:sequenced_assembly').displayName("PCB Press");
  e.create('pcb_part', 'create:sequenced_assembly').displayName("PCB Part");

})

I've the same issue here, I tried with a custom recipe insteed but it still not work.

this my recipe test

e.recipes.create.sequenced_assembly([
        'create:ochrum'
    ], 'minecraft:cobblestone', [
        e.recipes.create.mixing('kubejs:fusion_orchum', ['minecraft:cobblestone', '2x minecraft:gold_ingot']).superheated(),
        e.recipes.create.splashing('create:ochrum', 'kubejs:fusion_orchum')
    ])
        .transitionalItem('kubejs:fusion_orchum')
        .loops(1)

    e.custom({
        type: "create:sequenced_assembly",
        ingredient: [
            {
                item: "minecraft:cobblestone"
            }
        ],
        results: [
            {
                item: "create:ochrum"
            }
        ],
        sequence: [
            {
                type: "create:mixing",
                ingredients: [
                    {
                        item: "minecraft:cobblestone"
                    },
                    {
                        item: "minecraft:gold_ingot",
                        count: 2
                    }
                ],
                results: {
                    item: "kubejs:fusion_orchum"
                },
                temperature: "superheated"
            },
            {
                type: "create:splashing",
                ingredients: [
                    {
                        item: "kubejs:fusion_orchum"
                    }
                ],
                results: {
                    item: "create:ochrum"
                }
            }
        ],
        transitionalItem: Item.of("kubejs:fusion_orchum"),
        loops: 1
    })

And the kjs server logs send me this for both of them Error parsing recipe

create:kjs/4m9a3flxjqgwk5fhc22udyvv2[create:sequenced_assembly]: {"type":"create:sequenced_assembly","ingredient":{"item":"minecraft:cobblestone"},"results":[{"item":"create:ochrum","count":1}],"sequence":[{"type":"create:mixing","ingredients":[{"item":"minecraft:cobblestone"},{"item":"minecraft:gold_ingot"},{"item":"minecraft:gold_ingot"}],"results":[{"item":"kubejs:fusion_orchum","count":1}],"temperature":"superheated"},{"type":"create:splashing","ingredients":[{"item":"kubejs:fusion_orchum"}],"results":[{"item":"create:ochrum","count":1}]}],"transitionalItem":{"item":"kubejs:fusion_orchum","count":1},"loops":1}: Not a supported recipe type

Maybe a bug on the Create mod directly :/

Definetly not Create, I tried adding the recipe via event.custom() and it worked, definetly a mod problem. For now just use datapack-syntax recipes with event.custom().

Also I don't know if mixing and bulk washing works with Seq. Assembly. I've only tried with deploying and pressing.

After looking at your log, no, Create does not support your recipe types. I'd recommend sticking to deploying/pressing/filling as they are CONFIRMED to work. idk if draining works
