It seems that the Serafen quest still doesn't have a real ending. At least none of the patch release notes mentioned that this was fixed (as i write this, 1.2 is the latest version).
Could the developers comment on this please? Do you plan to fix this? If yes, when? Or is it intended this way? Since I saw this bug, I haven't played a minute. I'm quite disappointed.
