Patch not updating

[crucialfelix]

Patch seems not to be able to update the Instr:

Patch("fm.car1mod1", [49.midicps, 3, 3]).play; Patch("fm.car1mod1", [54.midicps, 2, 5]).play;

note: a bug related to this was fixed 7 months ago.

    Instr("car1mod1", {arg note = 49, modPartial1 = 1, index1 = 1, mul = 0.1;
        var mod, car;
        mod = SinOsc.ar(note.midicps * modPartial1,0, note.midicps*index1*LFNoise1.kr(0.5).abs);
        car = SinOsc.ar(note.midicps + mod,0,mul)* EnvGen.kr(Env.linen(3, 1, 3), doneAction:2);},
    [
    \midinote,
    [0.0, 20.0],
    [0.0, 20.0],
    [0.0, 1.0]
    ]);

just another simple example from the help-file which is also not working:

    Instr(\Pulse,{ arg freq=440.0,width=0.5,mul=0.1;
        Pulse.ar( freq, width, mul )
    });
    p = Patch( \Pulse, [ 300, 0.2, 0.1 ]);
    c = Patch( \Pulse, [ 500, 0.3, 0.1 ]);
    p.play;
    c.play;
