so 1. activate the quest and put in the command console " showquesttargets " and get the quest id
2. next, put in the console " player.sqs <quest id> "
3. finally, put in the console " setstage <quest id> <stage> " however i think you use the 2nd to last option (for me it was 250)
for me, i had to put in " setstage nq15 250 " and it worked for me
BUT!!!!!
there was a problem, the quest completed and i exited the building and my game crashed so i would recommend keeping autosave turned on
