Yeah, once you save your game with a bug, you're stuck with it.
I was very careful to make sure my quests weren't bugged before making saves. I learned my lesson from playing Oblivion and having a bunch of glitches in it.
If something didn't complete correct or I didn't get the next objective that I was supposed to, I reloaded and did it gain until it was right. I obviously got through this particular quest on the first try without getting it.
It also helps that I have the game guide and read through the quests people on here say they have problems with before I do them. That way I know if it's ending right or not. Without a guide, it's tough for anyone to know something isn't right until it's too late most of the time.
I understand what you're saying. But honestly, what reason would I have to claim I did something I didn't? I have no reason to come on here and lie about it. What does that gain me? It doesn't even make sense to come on here and lie about doing something.
No purpose at all.
I'm not some teenager coming here to troll people to get my kicks. I'm just a 42 year old gamer who's trying to help people when and if I can. If I can give someone a few suggestions that might work then why not. They may not work all the time but in my opinion, it's worth a try before starting a game over from scratch right?
Anyway, hope you can eventually figure out a way to finish it.
