I notice there is something seriously wrong with an O2 test calculation with a CAS(6,6)/CCSD. The reference energy is positive and nothing like the value in the previous CASSCF run.

Could this be a bug or am I doing something wrong ?

Thank you!

On a related note, are analytic gradients for this approach available?
I get a crash from the prop module when I try it.

Unfortunately, no analytic gradients are available with MCSCF references.
