this is indeed a bit strange. Check if the correct roots are
properly captured by the CI's initial guess routine. If not,
try to increase NSTGSS and NHGSS in $det.

>I faced a problem. I successfully got CASSCF(11,11) solution with two doublets and one quartet. I use SA-MCSCF for these states since they are sit very close to each other. The total number of states is 10. I did calculations without $MCSCF iforb=.t. sd=.t. $END. Then i added this keyword and reused optimized orbitals, but my solution was quite different. The state order before was D,D,Q, but with iforb=.t. it is Q,7... Is it normal effect of iforb or there is a pitfall somewhere here?
