Hello,
I am enjoying 0.81a but something "funny" happened: Around 217bc a region in roman territory turned "blue baktrian" and a region in baktrian territory turned "red roman" - as is, I can keep playing so far (212bc) - I'll list some...

Nervaea Belgaei and its recruitment became Baktrian
Its city (Bagacos) and buildings remain Roman (coastal clearing error)
At the same time...
Dayuan and its recruitment (celtic and belgic auxilia) became Roman
Its city (Alexandria-Eschate) and buildings remain Baktrian

I did try to get around this with "diplomacy" (exchanging territories...): the regions and recruitment were corrected but then the city and buildings became incorrect !

I am going to keep playing - I don't mind recruiting "unexpected units"; nevertheless, I would like to correct this.
Any ideas anyone?

Thanks
