I am trying ( without much success ) to make a campaign map that will work in game!

So far, I have only managed to make something which causes an instant CTD when you select a faction in the campaign selection and go to fire it up.

show_err doesn't kick in, and I have absolutely no idea what might be causing it.

Heres what I have done so far:

Made up a new cam[aign sub-folder, and checked that worked OK

Drew a new 'regions' tga.

Changed the descr_regions and descr_regions_name_and_settlement_lookup text files to match.

Then, I modified descr_strat to take out all the provinces I am no longer using. Ultimately, I will replace all the names with new ones, but I am using stock RTW names for now.

Rome and Latium still exist.

I am only using a small number of factions, and have completely removed references to the ones I am not wanting. I left in Slave and Senate.

The rivers and fords tga has been blacked out completely so I had no rivers where I didn't want them, and I have made sure no resources are sitting outside of proper faction lands.

descr_mercenary text has been amended to remove non-existant regions too.

I have run it through the TIME editor, and I don't get any error messages ( well...not now anyway!! )

With no troubleshooting info, I just don't know where to start!
