Issue Description:

I'm using KubeJS to modify the contents of the shulker box in the players inventory. I'm using let slotItem = inventory.getItem(slotIndex) and then modifying that item accordingly, modifying the contents of the items array. If the shulker Box is not held during this modification, it doesn't update the tooltip.

What happens:

Tooltip doesn't update

What you expected to happen:

That the tooltips update and show correctly

Steps to reproduce:

I'm using this kubejs code to modify the shulker:

event.player.inventory.getItem(slotIndex)`

and switching between

slotItem.nbt.BlockEntityTag.Items.addTag(i, {id: "minecraft:gold_ingot", Count:1, Slot:0})

and

slotItem.nbt.BlockEntityTag.Items[i].Count = newCount

And wrapping that in the player chat event to trigger it. I've set an according slotIndex and index.
This is not modifying the display Tooltip

Affected Versions:

• ShulkerBoxTooltip: shulkerboxtooltip-forge-4.0.4+1.20.1.jar
• Minecraft: 1.20.1
• Forge loader: 47.2.32
• KubeJS: kubejs-forge-2001.6.5-build.7.jar
  I don't think any other mods cause this.

Sorry, I see no obvious mod in that list that may cause the problem. Have you tried disabling half the mods the isolate the culprit?

Ok, yeah sorry for reporting, it doesn't happen without the other mods. There seems to be a mod that directly interfers with this tick. Do you have an idea which it could be?
this is a renamed mod list html, cause github doesn't allow html
modlist.txt

Is there any method that needs to be called to correctly register an nbt change?

That's really weird, ShulkerBoxTooltip checks for NBT changes each frame so this is not supposed to happen.
I tested in "vanilla" using /item replace in a loop and the tooltip updates correctly regardless on what inventory or slot the shulker is in.
Can you share a minimum setup using KubeJS so that I can check on my end?

So I've found the culprit. It's Recipe Essentials: https://www.curseforge.com/minecraft/mc-mods/recipe-essentials-forge-fabric this mod causes the gui to not update. Should I report this to them as I've noticed that this also affect custom model data?

newest version btw: recipeessentials-1.20.1-3.4.jar

@MisterPeModder

Any Update on this?

I missed your comments, sorry.
If the issue is not caused by ShulkerBoxTooltip, then you should report it over at the Recipe Essentials issue tracker.

ok thanks will do!
