Issue Detail

Treasure maps are becoming chunk ban items, I've got this with modded and some of the vanilla ones. Removing moonlight solves the issue, also getting this with moonlight alone.

Some of the information below might even be helpful:

I had the same issue, this happened to me over several versions of the library(I have the latest one right now) although, OptiFine_1.20.1_HD_U_I5.jar also has to be there.

Paper server: client disconnects when a FILLED_MAP is in an ItemFrame or inside of the player's inventory, however it does not matter, if an ItemFrame is held.
Singleplayer world: game crashes whenever a map is created/help, I don't know anything else
client disconnects even after this(Kotlin):

player.inventory.setItemInMainHand(ItemStack(Material.DIRT))
player.inventory.addItem(mapItem)

I crashed the first time on a singleplayer LAN, then again in just singleplayer. There was no error in either console on the server.

Anyways, here's my stack trace, if you'd like it:
crash-2023-11-27_18.26.41-client.txt

I can help with providing more information, if you need anything

this happens to me too, always when rendering a map on a item frame

Be sure server and client have same version

XDDD bro how do i even install moonlight on hypixel

Same as with any other server. Put it into the server mod folder

Does it work with a normal server? If not it's a paper issue, we can't be expected to have things work for paper

Its... a public server

Why even talking about this tho, of you are playing on a server and aren't the owner you are not the one that decide which mods to add or not

Then ask the admin....

bro? i wanted to install some client side mods only to play on various servers but cant because they use a library that can only function properly when installed on both sides, that truly doesnt make any sense bruh

Here the same Issue, it on an Paper server, the admin tried out to do on it, but it does nothing work here on our side

i had only added it on Client side,

i had added Also Fast Painting, but allways, with this two Mods, it Crash

Moonlight is required oh both servers and clients. I have no mods that are client only (and that thus require this) (besides better jukeboxes which could function client only in jank mode)

Dont use paper with mods. Paper is for vanilla! The fact that it seem to work with some mod combinations is merely a chance and such servers are known to break shit all the time becausae devs do not care about the modding environment. I remembr having issues with them completely disregarding dapack registries. Why would they as vanilla only has a set of hardcoded ones. This doesnt even come from me, its general consensus in the modding community and unless paper devs put effortin providing mod compat it wont happen
