>I am using NBO orbitals as starting orbitals for MCSCF. The system is Cs symmetric. I used symmetry during the generation of the NBOs. Also, line  $moorth symden=1 symvec=1 syms=1 tolsym=1d-7 $end was present during all calculations. However, if i start MCSCF four of my orbitals are bad. I am also using asis=.t. to keep my orbitals not orthonormalized.

>I played with tolsym but no luck. Is it known feature of NBOs to be symmetry broken or some workaround exist in this case. If needed, i may provide a file i used to generate NBO and input file for MCSCF (offline).
