ItemsAdder - "Unhandled exce t ion occurred in onPacketSending(packetEvent)"

Seno

Hi,

I got this error that often crashes my server or made him freeze for a moment. I noticed that this error appear everytime that an achievement's made by a player.

Minecraft version : 1.16.5
ItemsAdder version : 3.6.4-release-3
LoneLibs Version : 1.0.56

Can you help me please ? This is very annoying

Seno as you’ve stated on Discord, you’re using Arclight, please test plugin on Paper instead.

Then we could talk about issue

psycheer Alright, I was able to reproduce this in Paper. Ima post a Youtube video here in a hour with logs and all.

As you requested, here's the bug reproduced on a Paper server in video.

And here's the log from it :

Thanks in advance
Looking forward for your help

EDIT : The issue doesn't exist on ItemsAdder 3.6.3-beta-14 which I just tested. All works fine. BUT I still want to use the latest release of ItemsAdder. I assume that this "old" version of ItemsAdder had knowns bugs or dupe exploits ? If you told me that this version is ABSOLUTELY safe, then I'll go for it and that's all. Waiting for your answer

Nevermind, I just turned off the achievements thing

Ok it keeps happening. But now I really don't know what caused that

It's the same error. But has I do not have any information of what could caused that, I can't reproduce the issue.

BUT, as I've say on DIscord, after searching the same error message on the Discord, I've discovered that several people had the same issue as me, and they were on Paper too. So I am wondering if it's related to a ItemsAdder specific version ?

Protocol related errors can be because of wrong version of protocolLib for pre1.20.5

Download ProtocolLib 5.2.0-679 or 5.2.1-689

5.3.0 is 1.20.5+ ONLY

Well, it's the same thing. This is on 5.2.0 version of ProtocolLib. I can't found 5.2.1 version but let's be honest, it will be the same. Otherwise can you send me a link where I can download it so I can test ? Latest build of ProtocolLib's 5.2.0..

Also, I renew my question which was : The issue doesn't exist on ItemsAdder 3.6.3-beta-14 which I just tested. All works fine. BUT I still want to use the latest release of ItemsAdder. I assume that this "old" version of ItemsAdder had knowns bugs or dupe exploits ? If you told me that this version is ABSOLUTELY safe, then I'll go for it and that's all. Waiting for your answer

Seno cannot say 3.6.3b14 is safe but I suggest to report this onto GitHub as it looks like version incompatibility in my eyes as on Paper 1.20.4 all works correctly.
