Just a little something I found while wading through the files. Scythia and Pontus have special upgraded bodyguard units. In 1.2 (at least), all upgraded bodyguards have general_unit_upgrade listed in the attributes line of their units. However, this is missing for Pontic and Scythian upgraded generals, which leads me to believe that they won't upgrade together with everybody else. So, in the export_decr_unit.txt for the units "barb scythian general scythian" and "east pontic general" add general_unit_upgrade at the end of the attributes line. In other words, the attributes line should end up with:

hardy, general_unit_upgrade

for both units. I haven't tested this in the campaign, since it would be a long wait for the reforms etc., but I think this is how it should be, since it's like that for all other bodyguard units.

Cheers,
