Hello so I'm struggling to understand why is multisim telling me different outcomes in the exact same circuit with same values just in two different simulations. I have attached the photos for you to see the circuit of astable multivibrator. In one of the multisim simulations the values work perfectly I tried a new one with the same circuit and it's not working properly or not at all not even with different values selected in the margins of what is possible for such a circuit. By the way I forgot to tell that the transistors in both the simulation and my drawing are the "mpsa44". Thanks.
