I wandered into a Telvanni questgiver in Ember Keep. The questgiver, Jula Minthri accurately calls me mouth, but then refers to me as Lawman when I inquire about the quest. Picture attached.
In the quest "Find the Helnim Gang", you can interrogate Feladir in his prison cell. He says he's a member of the thieves guild, when in fact he's a member of the Helnim gang and you're here to get the gang to join the thieves guild.
Edit: To clarify, he says "I'm in the guild" if you ask him his background. This may be a dialog line added by another mod for members of the thieves guild, but nevertheless he shouldn't be a member of the thieves guild.
Items inside "Llaram Plantation,Manor" and inside the nearby shacks have no ownership, and a few containers outside are marked as being owned by Great House Redoran
