Sissak bug?

[JoniOdin]

Hi! I have a question about Sissak in Forgotten Sanctum:
Apparently I should be able to resolve this peacefully if I give him the Warden Contract. I do have this contract, but I can't give it to him, only say that I might look for it, which leads to fighting him.
Is this a bug, or am I missing something?

Here is the output-log and the DxDiag, if this helps.

Or, to repeat my question from the first post, am I just missing something and this isn't a bug?
