Bug Description

Server is 1.19.4
I recently upgraded my instance from 1.20.4 to 1.20.6 and noticed the empty spots in my shulker tooltips were skipped. I made sure this is a Via issue and not the Shulker Box Tooltip mod issue.

1.20.4 client:

1.20.6 and 1.21 clients:

This may not seem like a huge issue but it gets annoying on anarchy servers when you are trying to make a kit and need to get it right.

Steps to Reproduce

1. Install: 1.20.6 or 1.21 client. Mods: ViaFabric, Shulker Box Tooltip and Mod Menu
2. Launch
3. In the Mod menu, locate Shulker Box Tooltip and in it's settings toggle on "Swap Modes" and "Always On".
4. Connect to 1.19.4 server
5. Hover over a shulker box that has empty slots in between items
6. Notice the empty slots are skipped

Expected Behavior

Empty slots in the shulker box should exist.

Checklist

• I have checked if this is specific to ViaFabric platform, and doesn't happen when running it on other platforms (Paper/Sponge/Velocity/Waterfall).
• I have included a ViaVersion dump.
• If applicable, I have included a paste (not a screenshot) of the error.
• I have tried the latest build(s) from https://ci.viaversion.com/ and the issue still persists.

Does this continue when using real 1.19.4 client on same server?

[Kyuunex]

This issue does not exist when using a real 1.19.4 client on this 1.19.4 server. (not having Via installed)

[Kichura]

will be investigated then.

Couldn't seem to reproduce this issue, Can you try this with a clean world save?

This is a 1.20.4 client on fabric 1.19.4 client during my test run:

perhaps there is some miscommunication
This is what the shulker box in question actually looks like when being opened normally

and these empty slots get lost when hovering over with the mod

Tried to copy what your shulker box contains one-by-one and this is what i got:

From what i understand about this mod, It sorts the items that have less than 64 to the last slots and the rest seem to be sorted with another mechanism that get sorted otherwise no matter how scrambled it is. (Slime and Iron were in very last two slots)

here's a simpler repro and world save

client is 1.20.6, world save is 1.19.4 for the server

Still seems to be properly sorted, Is your config the default btw?

[Kyuunex]

this is taken on a native 1.19.4 client on the same server

regarding the config: In the Mod menu, locate Shulker Box Tooltip and in it's settings toggle on "Swap Modes" and "Always On".

[Kyuunex]

shulkerboxtooltip.json
this is my config file, rename to shulkerboxtooltip.json5 and put it in the config folder

Now i can reproduce, except i now managed to find the issue itself which tells me that this is not a viafabric-specific issue to some extent. Except if the mod was present on 1.19.4 server then it's busted on 1.20.5+ clients cuz of the custom payload packets being too large.

[Kyuunex]

This is a non-issue when I play on a 1.20.6 server with a 1.20.6 client (with the same exact Shulker mod). Which is why I figured it may be a Via translation issue.

[Kichura]

Going to try this with 1.20.5/6 to see if i can get anything else to change with this as the mod states it also accepts server-side.

[Kichura]

Ok it's not busted on 1.20.5+ servers anymore and it properly renders the contents in same slots as it's in actual view, meaning 1.20.4 and older are broken it seems.
