I made some quick checking with the latest version (3.30 Beta; including loyalty option, excluding Carthaginian senate option), and there seem to be some problems with those Provincial campaigns. First four provincial campaigns (Bosporus, Cyrenaica, Epirus, Galatia) seem to work, as they should but I cannot access to those last six ones from Julius Caesar to Syracuse.
After I quitted the whole game there is an error message that says “Rome Total War – Barbarian Invasion: Script Error in xc/data/world maps/campaign/custom/Bosporus/descr_strat.txt, at line 7452, column 68. You have chosen an invalid tile (191,167) for Idanthyrus (scythia).
Those new map changes seem to okay in most cases, but in some cases, the campaign map shows the wrong names. Here are those minor errors that I found.
In Bosporan provincial campaign the map shows name of Campus Sakae (Tribus Sakae) instead of Phanagoria (Sindica), and in Epirote provincial campaign the map shows the name of Chighu (Wusun) instead of Epidamnos (Illyria Graeca). In the Thracian imperial campaign, those Illyrian and Pannonian names seem to be okay.
Besides, in the case of Bosporan campaign Neapolis Scythica (Taurica) needs to rename for something else because Taurica as a region means Crimean Peninsula. Simple solution could be this:
Olbia > Scythia Minor and
Neapolis Scythica > Scythia Major. However, I could try to find out if there any better candidates that might suit for the current location of Neapolis Scythica.
Finally, in the case of Saba, Opone (Azania) probably needs to rename as Avalites (Punt) that would suit better for its new location.
CV, otherwise you have done a great job, despite of this bug report…
