Hello ilnem and welcome to the forum
I have moved your question to a new thread. I assume you are playing the Steam version of Nehrim?
Have you tried to solve the problem by loading a previous save?
Have you installed any mods or used any console commands?
Otherwise we will have a look at your problem!
Please send us a suitable savegame (as a file attachment under your message). Preferably a hardsave (i.e. a manual one). We need both the .ess file and the .obse file. Since the forum software does not allow .obse format as a file attachment, please pack it as a zip or rar archive in advance (with WinRar or WinZip, for example).
