Bugs

 * On the Pc version after talking with Keller and passing the Int/Per check, if you decide to hand over the chem ingredients and mention Contreras, and then choose to attack and kill Keller after he says you're under arrest, when you return to Contreras the result and dialog option will be the same as if you kept Keller alive and bribed him to play along and keep his mouth shut about the chem trafficking. (This is occurrs as of patch #2).
