Odd issue here, and I'm looking for advice. :-)

I found a graphical glitch with an MSQ quest 'Final Ignominy.' I researched and reported it via two forum posts that are now in 'Accepted Bugs' (can search for 'ignominy' there if interested).

I now have a new character and he has to do this quest. Is it okay for me to do the quest in spite of the glitch? I don't really have a choice b/c it is MSQ but feel like I'm breaking the game or cheating if I do. Is there any official thing from SE on what to do if this happens? This isn't exploitable by any means.

Bugs freak me out and I'm likely overreacting over nothing. Just want to make sure it is okay to do a quest with known bugs provided you are not gaining any advantage from them.

Thanks.
