Alright, so I changed part of the export_advice file to this:

¬-------------------

{Help_UI_Panel_Diplomacy_Early_Advice_Text_01_Title} Diplomacy Basics

{f_Early_Advice_Text_01_Text1} some text
However, now the game crashes whenever I try to start it up (it shows the start-up splash screen, then CTDs). I clearly screwed up in some critical way.
