Final Fantasy Hacktics

Hi! I am having a bug with the rumors. I am in the first chapter, just finished Fovoham Plains and the following rumors don't open new fights anywhere (don't know if they should either): Goblin Uprising, Emissary of Ramuh and Academy Rebellion. And the text that appears is from the vanilla FFT, as in the image. Truth be told, the Academy Rebellion oppened up a battle in Gariland against Daravon earlier in the chapter and the rumor had disapeared but it returned, with corrupted text.

Is it problably a bad ISO copy?
