The Bug:
The game output console is logged with errors regarding missing signatures from property textures when joining LAN worlds.
In my testing, this issue is exclusive to LAN worlds and cannot be reproduced on singleplayer worlds or multiplayer servers.
When joining a LAN world, the following is printed into the game output console:
[10:36:12] [Worker-Main-3/ERROR]: Signature is missing from Property textures
Steps to Reproduce:
Launch an instance of the game with logs enabled.
Get another player to start a world and open it to LAN.
Join the LAN world and look at the game output console.
Take note as to whether or not the game output console is logged with errors regarding missing signatures from property textures when joining LAN worlds.
Observed Behavior:
Errors are printed into the game output console.
Expected Behavior:
No errors would be printed into the game output console.

The core problem here is still present, but the error message is now slightly different. I'm not exactly sure when this change was made, but I've updated this ticket accordingly. Just leaving a note of this here.

Also happens on 23w31a when joining a single player world, but not every time it seems?

Affects Minecraft 23w32a and 23w33a (even in Minecraft Singleplayer)

just happen on my world for 1.20.2.
