Yngulf the Mute speaks the line that is innapropriate for his character (He's always silent and prefers to speak with gestures). The actual line should be "[Yggulf the Mute makes a cutting motion across his right eye.]". Having looked in CS, I noticed that this line is brought by TR_Hotfix.esp I downloaded from nexus.
1. Immediately after returning the stone of Septimia my character was detected yet the guards didn't acccost me for being in the off-limits museum.
2. When I spoke to the guards, they accused me of breaking the exhibit (AKA "Making a Scene" in the UESP quest notes). However, I did not resolve the quest in this manner.

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.
If you lockpick the doors inside the Zafirebel Bay Company to get into the upper or lower floors, you'll find the door you just unlocked is locked from the other side as well. This could cause the player to get soft-locked because many of these doors are lock level 80+.
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
