When offline player trying to join with Automodpack mod and TrueUUID he is dissconecting with:

[16:26:10] [Server thread/INFO] [minecraft/ServerLoginPacketListenerImpl]: NCTR88 lost connection: Internal Exception: io.netty.handler.codec.DecoderException: java.lang.IllegalStateException: Uncompressed size 2 is less than threshold 64

thanks for submitting your issue, ill take a look into it

[F1xGOD]

have your tried running it with the newest mod version by building from source?

[vovchekShow]

Im running 1.2.0 , i dont have tools for build from code right now

[F1xGOD]

please see #32
it had an attached 1.2.1 jar, or if this is not urgent you could just wait until i will be testing later and debugging with that specific mod you mentioned

[F1xGOD]

yes, that jar build expired on the temporary host website, so i will inform you once i test on my side

[vovchekShow]

Okay, i can drop my modlist / mods

[F1xGOD]

Its fine I checked the log, it's the clienthello issue, I will have to reproduce that error myself, In simple terms, this happens due to your mod Automodpack, also creating a custom login challenge

[vovchekShow]

How long you can fix that issue? Im asking because im waiting to restore stable server operation, that require both mods

[F1xGOD]

I'll get to it when I get home, in the meantime maybe one of the other devs might help you, yesterday you created the issue when I was already going to sleep

[vovchekShow]

Okay, thank you, no problem

[F1xGOD]

I have a question about the intended / expected behavior, do you want the server to work when players only have a single mod (automodpack) or is it okay if they will need 2, automodpack, and trueuuid, in case of the only one mod, I might have to open a PR to their mod because both of the mods interfere with players join

[vovchekShow]

I need both of theese mods, automodpack and trueUUID, because your mod fix my issue with new UUIDs on same accounts, and automodpack help players dont download modpack multiple times when new modpack update

[F1xGOD]

it currently seems to work if a clean client joins with both mods, but fails if they join without trueuuid

[vovchekShow]

When i use both of this mods, offline players cant join, but online can (im about microsoft auth)

[vovchekShow]

but i need offline too
