@games647 correct me if I'm wrong but we never change the inventory content of the player, we only hide it using fake packets.

[games647]

Yes that's correct. However, somehow this is version 2.6. @SimPham02 can you check if this really the correct version.

AuthMe-5.6.0-legacy and authme-5.7.0-SNAPSHOT

[SimPham02]

When I use version 5.6.0, it only happens occasionally, but when I use version 5.7.0, it happens more frequently @games647

[SimPham02]

At first, I didn't know what caused it; I thought it was due to version 1.21. However, a few other servers also experienced the issue and said it was caused by AuthMe

[games647]

We only hide the inventory from the user. So all items are still there. A relogin should also show this. Another issue could be if the user profile switches the UUID, then it's a new user. However, AuthMe doesn't change anything about this. You could also disable ProtectInventoryBeforeLogIn, that will disable our hide feature.

It wasn't hidden; I've been using AuthMe for almost a year, and when I updated to version 1.21 and used the latest version of AuthMe, this issue started occurring. In some cases, items in the ender chest also disappeared. My server is cracked, and the in-game behavior remained unchanged. Even I lost items, despite being the server admin. I just logged out and back in immediately, and the items were gone. I noticed this issue often occurs when logging out and back in quickly. My friend, who runs a server on version 1.20, is also experiencing similar issues.

i had this issue when im running 1.20.4 now running 1.20.6 some players lost their inv and endchest and spawn on world spawn point

authme version 5.7.0

[JericNisperos]

Same goes with me. We started experiencing this since the first day of our server last June 1st. We're on 1.20.6 before. We are now on 1.21 and still happens occasionally.

We've reached out to other plugin devs and even stripped down our plugin list to check what's causing it. There's a high chance that this is coming from AuthMe, CMI, Worldedit,Worldguard,Multiverse. But since some of the server owners I talked to don't use CMI,Multiverse, and even Worldedit, the only plugins left are AuthMe and Worldguard.

The reset inventory includes wiped Enderchest, reset Crafting Recipes and being teleported to the world spawn.

[krusic22]

WorldGuard hard depends on WorldEdit.... We need an actual plugin list.

I've figured this out. In 1.21 server loads the player's profile after ServerboundFinishConfigurationPacket is received. If connection is unstable, this packet may not land on the server and PlayerList.placeNewPlayer will never be called

However later when connection is timed out, quit events are still fired and AuthMe will save an empty player data here: https://github.com/AuthMe/AuthMeReloaded/blob/536af46b2b971355c9bdb90eccf357e697fed5cf/src/main/java/fr/xephi/authme/process/quit/ProcessSyncPlayerQuit.java#L30

I don't know what the "proper" fix would be here because I'm not familiar with AuthMe internals. It can be fixed by doing a if (player.getLastLogin() != 0) check but AFAIK this API is only exposed on Paper. So if you can rebuild from source, build AuthMe against Paper API and insert this check: if (player.getLastLogin() != 0) player.saveData();

[Lolip-p]

Yes. I also ran into this problem!

[Krissoofer]

@Kadeluxe Have you fixed it already?

[sgdc3]

Please try with build 2632 from out jenkins (https://ci.codemc.io/job/AuthMe/job/AuthMeReloaded/)

[unnamed199cz]

EDIT: WRONG call, Newest build may not have the issue

[unnamed199cz]

edited ^^ due to mistake on our server

Hello, we run a minecraft server that's also been dealing with the exact same issue. Seems to be AuthME as well, since our other server which runs on the same config (but isn't in offline mode) hasnt ever encountered this bug.

[sgdc3]

@CyberHydra have you tried the latest dev build from https://ci.codemc.io/job/AuthMe/job/AuthMeReloaded/ ?

We've installed it right now. Hopefully it will fix the issue. I'll keep you informed.

@SimPham02 @t4ba @JericNisperos @Kadeluxe @Lolip-p @Krissoofer @unnamed199cz @CyberHydra is the issue fixed in dev builds?

@SimPham02 @t4ba @JericNisperos @Kadeluxe @Lolip-p @Krissoofer @unnamed199cz @CyberHydra is the issue fixed in dev builds?

This seems to be the case for our server. I've not heard of this bug happening anymore.

[Kadeluxe]

@SimPham02 @t4ba @JericNisperos @Kadeluxe @Lolip-p @Krissoofer @unnamed199cz @CyberHydra is the issue fixed in dev builds?

Yes, it was the only cause of that issue

AuthMe no longer calls Player.saveData when player quits, most likely it comes from another plugin then or you have a whole different issue (in your case the cause of the inventory loss is different)

Do you know if any of these plugins would be causing this issue? I installed InventoryRollback for a fall back just in case

better test plugin one by one and try installing the authme 2636 and fastlogin new version https://ci.codemc.io/job/Games647/job/FastLogin/1326/

It's normal that the plugin weighs so little, on spigot it weighs about 16mb???????????

[krusic22]

Yes. The required libraries are now fetched at runtime.

The bug is still up we host our servers using Aternos(Cracked/Offline) Paper 1.21.1 AuthMe 5.6.0 DiscordSRV 1.28.0

We only have 11 players playing in our server and it happened twice with different player and same event where:

1. a player disconnected(Both having Internet issues)
2. Reconnected(Right after)
3. Enderchest/Inventory/Crafting Recipe reset(However his statistics still remain)

Here's a what happened: -player named 284Hi359 disconnect and reconnects

-His player statistics from Aternos(after the Inventory/Enderchest/CraftingRecipes)

I will try to disable AuthMeReloaded and I'll be back if the problem reoccurs. Ask me questions if needed.

i think Aternos not allow you to upload jar so you must contact they support to install the new version from here https://ci.codemc.io/job/AuthMe/job/AuthMeReloaded/ and not 5.6.0
