    Antique Cities: Requires version 1.0 but mod is not found on client.


    but i swear this "Antique Cities" mod doesnt even exist,ive checked the curseforge page for rlcraft and theres no mention of this mod either.
    Is it an alias for some mod?

    Does the modpack version on your server match the modpack version on your PC

    Try reinstalling the modpack on your PC. If it doesn't work then keep a backup of the server and try reinstalling the modpack on the server
