Apology accepted and as to your question, I had already been using an old save when it happened, though admittedly maybe an older save would work better, as I haven't tried yet, I.e. I'll try and sort of thing when I have the time and let you know how things work out on that front.
you're welcome; anyways, bad news: did what I said and tried an older save file, only to run into the exact same problem when I got to the tower later on, I.e. I'm not entirely sure what's going on here, but I'm sorry to say that it's entirely possible that there might still be some bugs that are still in the game at this point in time :|
