Roman and Baktrian city "switch" ?

[Domitio]

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

That is an error that was previously attributed to not deleting the map.rwm. Since you shouldn't have to delete the map.rwm with 081a, that is quite odd.

are you using an old 0.81 savegame with 0.81a?

Thank you for responding.
I did start a new 0.81a campaign, but I am also using a 0.81 savegame (where the "switch" happened) - So, is that the reason ? Is there something I can do ? track it down to one of the scripts...? :hippie:

Well 0.81a is not savegame compatible. Such things happen when you use an old savegame in the new version. Nothing you can do except playing your new campaign. ;)
