Which description text are you referring to? The one when you select it from the provincial select screen and text appears in the box to the right?
I know the provincial campaign I worked on for M2 changed the description.txt file, but then that's for M2(was my understanding though that it was legacy code from Rome). The problem I've been having isn't the description itself but the name above the description box on the right hand side of the selection screen. Odd.
It's possible modifying one of these lines in the menu_english might work(looking at M2, but they seem to be in Rome as well):
Code:
{UI_PROVINCIAL_CAMPAIGN_DESCRIPTION}Campaign Description
{UI_PROVINCIAL_CAMPAIGN_SELECT}Select Campaign
{UI_PROVINCIAL_CAMPAIGN_SELECT_FACTION}Select a faction
{UI_PROVINCIAL_CAMPAIGN_SELECT_TOOLTIP}Select custom campaign
{UI_PROVINCIAL_CAMPAIGN_TITLE}Custom Campaigns
Either appending the name of the campaign(based on folder or what it's called in the descr_strat) after "PROVINCIAL_CAMPAIGN" or perhaps in place of it. For example:
Code:
{UI_PROVINCIAL_CAMPAIGN_MY_CAMPAIGN_DESCRIPTION}Campaign Description
{UI_PROVINCIAL_CAMPAIGN_MY_CAMPAIGN_SELECT}Select Campaign
{UI_PROVINCIAL_CAMPAIGN_MY_CAMPAIGN_SELECT_FACTION}Select a faction
{UI_PROVINCIAL_CAMPAIGN_MY_CAMPAIGN_SELECT_TOOLTIP}Select custom campaign
{UI_PROVINCIAL_CAMPAIGN_MY_CAMPAIGN_TITLE}Custom Campaigns
or
{UI_MY_CAMPAIGN_DESCRIPTION}Campaign Description
{UI_MY_CAMPAIGN_SELECT}Select Campaign
{UI_MY_CAMPAIGN_SELECT_FACTION}Select a faction
{UI_MY_CAMPAIGN_SELECT_TOOLTIP}Select custom campaign
{UI_MY_CAMPAIGN_TITLE}Custom Campaigns
Lastly consider specifying the string in "expanded.txt". Like:
Code:
{MY_CAMPAIGN}My Campaign
{MY_CAMPAIGN_DESCR}Here's my desc
{MY_CAMPAIGN_DESC}Here's my desc
{MY_CAMPAIGN_DESCRIPTION}Here's my desc
