where are the (custom?) battle files?

[max_minimod]

Hi, I wonder where the files fore the battles are hidden:
I work on a mod, have created an own mod folder, all worked since months. Now sadly since yesterday due to a PC-crash the battle on ' british grassland' dont works anymore (location is in the open sea and units die suddenly after start). All other battle-grounds work.
Surprisingly in custom_locations nothing has changed and in orginal BI and RTW the grassland battle still works ok.

So I wonder where are the additional files hidden, what files I have to copy again from my BI folder to my mod-folder to fix that?

(sorry I have not found any info in the forum yet besides custom_locations)

Well, if the map has changed since the last test you did on British Grassland, the coordinates in custom_locations.txt might now be pointing in the sea. Have you checked that they are still valid? (it isn't very clear from your post)

Yes they are the same like in orginal, that's what is confusing me.
'
custom_location British Grassland
{
location 123 96
image data/menu/grass1.tga
sett_locked no
summer no
}
'
Also I have not changed the map files on that part,... exept changed cities locations in map_regions.tga... ah! ...maybe thats the prob?

I don`t know if that causes a CTD, but check that the location from custom_locations is not the one where you`ve moved a city. You can see the correct in game coordinates using the map_regions.tga if you flip it upside down in the image editor that you`re using.
Also, somewhat related... In rtw there were a few battles with custom tiles. Like Grassy Flatland and Londinium. Those are not mentioned in custom_locations, but in the descr_battle file that each has. All of them having their own sub-older in Rome - Total War\data\world\maps\custom. If you make changes to your map don`t forget to edit the coordinates for these ones too.

Thank you Aradan and florin8o, I was able to fix it with your help.
The prob was I deleted the old BI-campain in base folder, so the positions on custom_locations pointed to my new map, where it had open sea on that position.
Thanks again.
