Your patches are incorrect. See
http://salilab.org/modeller/9v1/manual/node23.html for an example.

You have:

This should be:

>     def special_patches(self, aln):
>         # Acetylate the N terminus
>        self.patch(residue_type='ACE', residues=self.residues['1:'])
>         # Standard C terminal patch
>        self.patch(residue_type='CT3', residues=self.residues['238:'])

BTW, the standard C terminal patch is CTER, not CT3.
