Having a few issues with this Fortress.
Now, to give some background, I'm not 100% if it's the fortress itself, or my install. The game was working great, then one fine day, upon booting up my PC, it suddenly asked me for my Oblivion disc. It's never done this before. I put it in, and everything went fine. Nehrim loaded up, etc. However, it seems now (maybe it was always like this and I didn't notice,) my save files are named per session. What I mean is, instead of me loading up Save 8, and then saving again with Save 9, Save 8 becomes Save 1 if it's my first save that game session. It continues to rise (Save 2, 3, etc) until I reload the game, then it starts back at 1.
That's one issue, another is that I'm starting to run into books what are in German. Most of the books are still in English, but maybe 1 in 10 or so is still in German.
Now to the real issue.
I went into Faltrin Fortress, and killed everything I could, and then I went to the basement. Before going to the room with the skeleton (behind the Large Wooden Door,) I heard fighting on the other side. I go through the door, and the skeleton is one hit away from death. Hmm, ok. I finish it off, and then I notice I'm taking damage. There's something invisible which I can't target that keeps attacking me. I looked the fortress up on the wiki, and saw no mention of anything invisible. I promptly ran out and closed the gate behind me, locking whatever is hitting me on the other side. Whatever it is seems to have projectile attacks, as until I go up the stairs to get out of the line of sight, I keep taking damage.
Is this normal? Am I to look for a "See Invisible" spell, or is there an issue with my game?
