Well i have the disappearing text aswell, but i didnt pay much attention yet, when it occurs....
what i noticed is, that i seem to get debug messages, although i didnt enable the cheat menu/debug option of the mod.
Next time i will have a look when exactly the texts disappear and what kind of messages i get.
I'll edit my post, if there arent too many posts after this
Edit:
Just found another thing...
The faction relations to me are somehow messed up, before i had a relation of 100 to the nords, -100 to another(kerghit) and i think -60 to the sultanate,
now after installing the mod, i have -40 relation to the nords -40 to kerghit and 0 to sultanate if im right, i might check that over again, after sleeping a bit.
Though im not at war with the nords until i captured a city. I noticed that, after i captured a city and it wouldnt let me into the city managment for letting some garrison there. It threw me back to the menu, to choose siege or sneak into city. Then i hit siege again, thought it was a little error, but always the same, just that i dont have to fight anymore, as it has no enemys anymore. After that nords were at war with me, because well....it was already nord, just noticed that in the next dialogue with the king as there was a made peace option.
It's the first time i try this mod, i use a native savegame(clean, i only had some retextures) with the compatibility patch, as i already played 390days ingame. Imo its clearly due to the old save, new game of course had no issue accoding relations. I hope im wrong though, and it can be fixed, dont want to start all over again yet.
ahh forgot to say its the expanded version^^
