Behind the scenes
Ada's dialogue contains several pop culture references:
 * The line "Resistance is futile!" refers to the Borg from Star Trek''.
 * Spoken after using a terminal, the line "Using a keyboard? How quaint." refers to the same line spoken by Mr. Scott in Star Trek IV: The Voyage Home.
 * The line "it's like 'poetry in motion.'" is a reference to the 1961 song of the same name by Johnny Tillotson.
 * Spoken in any school location, the line "If you don't eat your meat, how can you have any pudding?" is a reference to the song Another Brick In The Wall, Part 2 by Pink Floyd.

Bugs

 * During the quest A New Threat, when one has to install the radar beacon on Ada with the robot workbench, only the option to modify the legs will be available, making the quest impossible to complete. A possible fix is to shoot Ada until she is crippled.
 * Ada can be commanded to pick up an infinite amount of items using the command action, resulting in unlimited carry capacity.
 * When commanded to hack a terminal, Ada won't acknowledge the command and continues to behave as if it was never given. Possibly fixed by restarting the game.
 * Ada will sometimes disappear without a trace. May be fixed by selecting a new companion.
 * Ada might not recognize being present during the final encounter with the Mechanist, and may ask the player character what the Mechanist said to them.
 * When first responding to the caravan distress call, nearby raiders may interrupt the conversation, stalling the conversation. Can be fixed by first clearing the area of raiders.
 * Ada's pathing may sometimes glitch, resulting in pursuing an unnecessarily long or impossible route.
