Problem with just one Civilization - Python Error

[kiwitt]

When I start my scenario, I can load all nations except one (U.S.S.R.) and it gets the error below, just before I get a CTD.

PythonErr.log

Traceback (most recent call last):

  File "CvWBInterface", line 47, in applyInitialItems

  File "CvWBDesc", line 1720, in applyInitialItems

  File "CvWBDesc", line 1152, in applyCity

  File "CvWBDesc", line 862, in apply

RuntimeError: unidentifiable C++ exception
ERR: Python function applyInitialItems failed, module CvWBInterface

Steps I have tried:

1) Open scenario in worldbuilder. All OK
2) And placed every type of unit on the map successfully
3) Created a city and added in every available building successfully
4) Checked every unit's UNITAI settings are correct
5) Ran a civcheck for all artworks and no errors found

My mod uses the standard - CvWBInterface.py (and CvWBDesc.py files from Beyond the sword in their original locations (..\Beyond the Sword\Assets\Entrypoints\ and ..\Beyond The Sword\Assets\pqWB\ respectively)

I'd check the all XML concerning the USSR one more time. Also the team and player entries in the WBS file.

Make sure you don't have a plot with two cities on it in the WB save, too. Or some other issue with a city in the WB save. That particular line in CvWBDesc.py is trying to add a city to the map and failing to do so.

1) I'll recheck all the USSR XML codes
2) I'll recheck all the USSR cities
