Bugs

 * Sometimes after leaving the quest in the memory den, you can get stuck with the memory lighting effect. This causes a desaturation of colors, and turning many things grey or blue, as well as adding a distinct blur to the foreground.
 * Sometimes after leaving the Memory Den, you can be stuck in the quest, without it finishing, and no way to go back to the memories in order to complete the quest objective: "Explore Kelloggs Memories.". Valentine will be missing, and Doctor Amari will be "Busy". If on PC, the console ('~') command "setstage mq202 320" will finish the quest. "setstage mq205 15" will start the next quest in the series.
 * Sometimes the quest will not begin after the conversation with Nick Valentine and Piper. Reverting to a save before the conversation may help.
 * Sometimes after speaking to Doctor Amari and being asked to sit in the lounge chair, when going to sit in the chair you are unable to do so since "You cannot complete this action in combat" despite not being in combat with anyone. There is no known fixed to this as of November 14 2015. [PS4]
