explicitbond error during excited state optimization

[saumik-psi]

During the excited state optimization of the molecule, some bonds (heavy atom to hydrogens) are becoming longer and thereby I am getting following error,
EXCEPTION RAISED: Internal coordinate transformation currently requires that we have only one molecule -- consider using "explicitbond"
I reran the calculation starting from different initial structures, however, same problem persists. I checked the orbitals and those are fine. Can you please suggest me how to solve this problem?
Thank you in advance!
