Version:
ProtocolLib v5.2.0-SNAPSHOT-679
Java Version:
21.0.3
Server:
1.20.6-124-0fcf3e3 (MC: 1.20.6)
this is what it asked to send here

will the dev build #694 worK?

Depends on what you are doing with it.
It's the next step, but still has issues with packet creation...

my only requirement is to run orebfuscator thats all

orebfuscator informed me that protocillib was a dependency thats why I installed it lol

im not sure whats happening
but my server is a spigot 1.20.6

Not in the latest dev build, obtain the latest here

And again a candidate with an old build running on 1.20.6 :/
Try to use ProtocolLib build 689... (it's not fully working on 1.20.6 yet, but way better than build 679!)

heya thanks a lot for the quick response but I downloaded the first version available on aternos...so it might need to be updated on aternos?

Use the link that @EuSouVoce posted and get the latest dev build from there.
