Un-stackable Items

[PhoenixCodingStuff]

❗ Checklist

• I am using the official english version of Slimefun and did not modify the jar.
• I am using an up to date "DEV" (not "RC") version of Slimefun.
• I am aware that issues related to Slimefun addons need to be reported on their bug trackers and not here.
• I searched for similar open issues and could not find an existing bug report on this.

📍 Description

All items prior to updating to 1.20.4 are not stackable with items after updating to 1.20.4.
The only way to fix it that I have found is to either get an admin to replace it for you which is not feasible replacing millions of items.
The other way I have found is that you can place and break head items to fix it, but again it is not feasible placing millions of items.

There was no resource pack added during this time period

📑 Reproduction Steps

Make 1.20.2 [or any older version] server.
Get few items.
Update server to 1.20.4.
Get the SAME items and figure out those do not stack.

💡 Expected Behavior

Items should stack and older items should automatically update.

Have you not made any changes to plugins in the update?
There is an extra tag added called extra{}

[PhoenixCodingStuff]

This is what I did before the update:

• Stop the server.
• Make a backup.
• Update GriefPrevention, DiscordSRV, Geyser, DracFun, Via* and ProtocolLib.
• Removed LiteX, Adapt and AE.
• Upload the purpur build from website.
• Started the server.

I did not add any new plugin during the update.

Here is a paste of 4 items [2 new 2 old not in order] -> https://paste.gg/p/anonymous/8026be36e800485988ee47ac05ed0d16

Edit: I messed up copy pasting so updated the paste link

[J3fftw1]

This is due to a change in nbt order in the 1.20.4 update we can’t really do anything about this.

ah okay sad, I hoped there would be some update mechanism but I think I will try to make one
