I used "Yusuf's Turkish Kijil" and "Mehmet's Dagger" in The Renegade mission, but unfortunately game stopped working when I hit with them to Shahkulu. I tried 3 times, but everytime game stopped working whenever I hit him with these weapons. I passed mission with hidden blades. After that I replay memory, and use another sword for mission and there is no error. Have these weapons problem in that mission ?
