object strange behaviour

The object instantiates when creating it manually with the object box (and works fine, all the functions work, doesn't crash , works like it's supposed to), while fails to instantiate while loading a saved max patch (with the object in it). Because of this i'm unable to debug my external.

For what it's worth i'll post my new and main function.

void main()
{
    setup((t_messlist **)&burges_class, (method)burges_new,0L, (short)sizeof(t_burges), 0L, A_GIMME, 0);
    addbang((method)burges_bang);
    addmess((method)burges_secondList,"secondList",A_GIMME,0);
    addmess((method)burges_firstList,"firstList",A_GIMME,0);
    addmess((method)burges_setDimensions , "setNumberOfDimensions" , A_LONG , 0);
    addmess((method)burges_reset , "reset" , A_NOTHING , 0);
    addmess((method)burges_save , "save" , A_SYM , 0);
    addmess((method)burges_open , "read" , A_SYM , 0);
}

void *burges_new(t_symbol *s)
{
    t_burges *x;

    x = (t_burges *)newobject(burges_class);

    x->m_maxRows = 1000;
    x->m_maxDim = 300;

    // create two-dimensional arrays of doubles
    x->m_xx = dmatrix(1,x->m_maxRows,1,x->m_maxDim);
    x->m_yy = dmatrix(1,x->m_maxRows,1,x->m_maxDim);

    x->m_firstListRows = 0;
    x->m_secondListRows = 0;
    x->m_numberOfDimensions = 0;

    x->m_outtype = A_GIMME;

    x->m_out = listout(x);

    SETLONG(x->m_args+1,0L);
    SETLONG(x->m_args,0L);

    return x;
}

Thanks!
