game[] variable resetting after map_restart

[serthy]

I have the following code:

		Init()
{
    doexit = false;

    if( !isDefined( game[ "init" ] ) )
    {
        game[ "ranks" ] = [];
        game[ "rank" ] = [];

        LoadRanks();

        doexit = true;
    }

    /#
        printf( "game[ ranks ].size = %\n" , game[ "ranks" ].size );
        printf( "game[ rank ].size = %\n" , game[ "rank" ].size );

        assert( game[ "rank" ].size > 0 );
        assert( game[ "ranks" ].size > 0 );
    #/

    if( doexit ) // simulates s&d round-end
    {
        wait( 5.0 );

        printf( "game[ ranks ].size = %\n" , game[ "ranks" ].size );
        printf( "game[ rank ].size = %\n" , game[ "rank" ].size );

        wait( 0.05 );

        map_restart( true );
    }
}

LoadRanks()
{
    ranks = SqlQuery_GetRankForType( "account_group" );

    for( j = 0 ; j < ranks.rows.size ; j++ )
    {
        rank = spawnStruct();
        rank.ranklevel = int( ranks.rows[ j ][ "Rank" ] );
        rank.name = toLower( ranks.rows[ j ][ "Name" ] );
        rank.id = game[ "ranks" ].size;

        game[ "ranks" ][ rank.id ] = rank;
        game[ "rank" ][ rank.name ] = rank.id;
    }
} 
	

This loads the ranks from a mysql table to the game-variables.
I wanted to avoid loading the ranks every round on S&D, so i stored the information in the game[] variable rather than in the level.variable.
However: after a map_restart the game[ ranks ] array is empty (size = 0) and the game[ rank ] array stays filled. (in the code example, the 2nd assert fires)

I do not delete the array in my code (after 5 seconds, before the map_restart, the array is still filled
I renamed "ranks" to "test_ranks", as maybe the name is special and overritten by the engine, but the result is the same

Am I missing something?
Do I misuse the game-variable?

Maybe only primitive types can be stored across a map_restart (and not spawnstructs)?
