Bug Description

I have an issue with players on higher versions not being able to see each other. They go into a "Ghost" ("invisible") state, the server is 1.12.2. I was on the game version 1.19.4 and my friend was on 1.20 when this happened. However, I believe it's any version after 1.16 when I join with 1.8 I can see him but he can't see me.

SIDE NOTES:
Server Version 1.12.2
Latest Versions of ViaVersion, ViaBackwars and ViaRewind
Player displays on /glist and able to message the player
I tried many versions 1.16 players are shown. Higher versions aren't
Sometimes happens, sometimes not.

Screenshots are between 1.19.4 and 1.20.

Steps to Reproduce

Log in 1.20 or similar into a 1.12.2 server using latest Versions of ViaVersion, ViaBackwars and ViaRewind.

Expected Behavior

Players should not be invisible

Additional Server Info

I tried running the server with no plugins, still happened. Also tried many via* plugins versions

Checklist

• Via plugins are only running on EITHER the backend servers (e.g. Paper) OR the proxy (e.g. BungeeCord), not on both.
• 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.

The """ghostbuster team""" has been called in but sadly, this problem could not be reproduced:

Can you test with ViaVersion 4.9.3-snapshot and ViaBackwards 4.9.2-snapshot to see if it persists?

I just tried it and the error persists there are small chances that the players can see each other.

Then it's a third-party plugin or bad world save causing players not to be displayed correctly, Please perform a binary search to see what's causing the fault of it.

I have tried everything even worlds and no plugins

Since this doesn't look like a clean world save and because prefixes are still shown - this doesn't seem to be tested; could you run a test server on your local machine with viaversion installed and see if it somehow persists, because i could not reproduce this whatsoever.
