Perhaps if people are going to continue posting on their experiences of when and where they witnessed this kind of activity happening, it would be more beneficial to the dev team if people actually included more details then "in act 3".
ie. Act - Area - Was the area cleared or still full of mobs? - Were you near environmental effects? (Such as mortars falling on the map in Skycrown or FoS) - How long did your bot continue to attack "nothing" - did it move on or did you have to stop it manually? - etc, etc, etc.
I mean I see no harm in people noting that they've experienced it too, but if they want to dev's to do something about it then the more information you provide them (about any details, big or small) would probably help to speed up any action the dev's could or would be able to take.
If you're going to go to the Doctor's office because you think you've caught the Flu, it might be beneficial to tell him more info than "I've been coughing alot".
