Hello there!
First of all, many thanks for this awesome mod. It really adds a lot to the game and makes M2TW trully enjoyable.
Now to the CTD I encountered:
I'm playing Milan and everything (even clicking on heretics) works, apart from when I click on a Hungarian family member. I always get a CTD with an unspecified error in the log. This has not happened to be before I had 1E installed.
I have the German 1.2 version of the game, installed all sound packages according to the instructions and use the newest LTC mod.
Thank you for your time.
P.S.: I just encountered a second, similar bug: As soon as I click on a rebel army, the game crashes.
P.P.S.: I tried using the vanilla files and as it appears, the error is in "events.dat". As soon as I use the events.dat from Xenophonia, rebel commanders and hungarian faction members crash my game, as soon as I click them. I therefore think that the events.dat from Xenophonia somehow corrupts the soundlinks in the German version of the game. Also, when playing Hungary in a custom battle, the people don't say anything, another hint in this direction.
