There is always the possibility that you have a circuit that has multiple operating points - and that the difference in order of processing is causing the numerical algorithms to prefer one solution over the other (i.e. both are correct, but there's an element of luck to which solution you'll get).
However, the most likely explanation is that the circuit is not in fact identical. I don't know how you're generating a flat netlist (this used to be supported in the spectreS interface, but not in the newer spectre interface) - it might just be that you have two different schematics - in which case perhaps you entered something wrongly.
I'd compare the netlists and see if you can spot any difference.
Best Regards,
Andrew.
