Because MOPAC does not unambiguously announce the optimized structure, Open Babel 2.3.2 extracts the initial structure from its cartesian translation. The actual structure appears ~50 lines below a "GEOMETRY OPTIMISED" statement which precedes energy results.
The optimized structure may be in either MOPAC cartesian or MOPAC Z-matrix format.
The MOPACFormat::ReadMolecule(...) method needs a rewrite to handle this.
