You could call me a hoarder in Skyrim. This urge for obtaining each weapon early and as fast as possible is what lead to me getting the Chillrend early as well. As most may know, the Chillrend is in the Riftweald Manor and associated with the Thieves Guild quest: The Pursuit. This is where my issue is. I managed to get the Chillrend early and also grabbed Mercer's plans (I wasn't aware of their significance) early too. This lead to the problem with starting the quest: The Pursuit, until I returned the plans back to where they came from - the desk in the Riftweald Manor. I then began this quest (The pursuit) with Mercer's plans back in their original location, however, when Brynjolf sends me to go fetch them, which starts the objective of 'Discover evidence of Mercer's location', the objective doesn't mark as 'completed' when I pick up the "Mercer's Plans", preventing me from furthering in the Thieves Guild. So how do I resolve this and make it register that I did, in fact, 'discover evidence of Mercer's location'? I'm a level 37 and I DO NOT want to restart, I just want the Nightingale armor...please, any help would be greatly appreciated.
