Please mark mod as client side only.

Mark the mod as client side only please, Thanks.

Do you mean in the description or the code itself? I can certainly put it in the readme, but there's no way that I know of to do it in code.

[Claycorp]

in your @mod you need to put @Side.CLIENT or something of the sorts, I don't have anything on hand to know exactly what it is. Then it won't load on servers and cause crashes making it easier to use and gives less issues for you.

[MrNerdy42]

Adding a @SideOnly(Side.CLIENT) annotation to the main mod class does not prevent the mod from being run on (and subsequently crashing) a server. I don't know of any other way prevent my code from running on a dedicated server.

Depending on the Forge version you can specify it in the Main Mod annotation, with @Mod(clientSideOnly = true) or, if that's not available, use the manifest by adding this to your build.gradle:

jar {
    manifest {
        attributes 'ModSide': 'CLIENT'
    }
}

Thanks, @Mod(clientSideOnly = true) works perfectly.
