This is an interesting response, because I also had problems with cloning my object. Currently I'm copying every field in the object by hand to the new object. 
sub clone
{

    my $self=shift;
    
    my $clone=new Board;
    
    $clone->{rep}=$self->{rep};
    
    $clone->{castling_rights}=$self->{castling_rights};
    $clone->{half_move_clock}=$self->{half_move_clock};
    $clone->{full_move_number}=$self->{full_move_number};
    $clone->{ep_pos}=$self->{ep_pos};
    
    $clone->{turn}=$self->{turn};
    
    return $clone;
    
}
