While playing thieves guild's side quests I'm facing the following issue:

The quest "That Which Was Lost" (second side quest from Velsa) has a stopping bug. I cannot aim the NPC which holds the keys for Tashmin's chains in Skywatch for pickpocketing.
That NPC has a quest marker hovering above his head, but no name or description and is just not recognized as a potential target for thieves.

I could play that quest last week with two of my chars (Altmer and Khajiit) without any problems. Today I tried two different chars (Bosmer & another Khajiit) on two different PCs; both of them facing the problem described above.
This is annoying, since the achievement "The Lady in the Cistern" is out of reach for these characters, because the document "Velsa's Theory", which is necessary to complete this achievement, does only drop if that quest is completed.

I'm playing on PC EU (German client).
If you need more information, please let me know.
