After recently going through Esseles a few times, I've been experiencing a few glitches, along with the other people I was playing with. In the first run, our mouse pointers disappeared from the screen for 30 seconds. In the second run, when the ambassador walks into the room, we couldn't see any of the 3 conversation options and the camera was pointed toward the sealing. We also experienced another glitch with the ambassador. In a later conversation near the end of the flashpoint after you defeat the sith apprentice, she started rolling on the floor and jumping back up... I'm just putting these out there so that they may be fixed sometime in the future.
