Hello Darmuh,

Thank you for this incredible plugin which works perfectly, at least for version 1.1.1

I made a set of mods that work in vanilla without players needing to install anything, since you updated your mod to 1.5.0 it is impossible for players to join the game :

in console : [Netcode] NetworkConfig mismatch. The configuration between the server and client does not match

So for the moment I managed to put back the old version which still works with V49 but it would be super cool to be able to use 1.5.0 in vanilla like the old one ;)

Is it possible for you to make version 1.5.0 compatible in vanilla like the later version?

Thank you in advance for reading

So this error occurs because you have networking enabled. You'll need to go to your config and disable networking via this configuration option:

If you're not using a mod manager it is this option:

I would 100% recommend upgrading to 1.5 not just for the new features (even though disabling networking does disable some things) but also as the code has been improved quite a bit from 1.1

I'll leave this issue open just so others can see the answer, as this is a common question being asked.
