Ada says "objective achieved" independent of mission progress
Bug that has been in Prime since forever.
Start a mission which requires for example hacking 20 portals. Ada will then say "objective achieved" the next 20 times you hack any portal, even portals that are not even part of the mission. After Ada said "objective achieved" 20 times, she will stop saying it even when the mission is still ongoing and you are hacking the correct portal in the current mission.
Start a mission which requires for example hacking 20 portals. Then abort the mission. Ada will still say "objective achieved" when hacking the next 20 portals even though the mission was aborted and there is no active mission.
