Bug persist again in the same place. Unfortunately I have to leave the game. Thank you anyway.

yes. I am playing the Steam version of Nehrim. I tried to solve the problem by loading a previous save several times.

After talking to Kim and to little Aetherna thief, I can't cross the bridge because game freezes. I tried several times, but without success. The game always freezes in the same place. I can't finish the main Quest.
