When going into the holding area where Goblin Sazza is, the following happens.
Once you complete your persuasion/intimidation etc to save her life, there is an additional dialogue option and cinematic that can take place as the Tieflings walk away.
After saving Sazza, I spoke with Memnos which initiated a cinematic cutscene of Arka talking about killing Sazza even though she is still alive.
Combat issues after freeing Sazza and taking the underground secret passage area behind the holding area. Engaged the Goblin group using the rogue PC from the story. He killed the main Goblin with the sneak attack which caused the screen to black out, but you could still hear game play and movement taking place. Once the game crashed, a crash report was submitted.
