another glitch?

this is a really strange glitch. i can see how the agents get to the HQ! as you may know, i am not a agent. so how did this glitch happen? here's how the glitch is done

1. go to the underground agent wall
2. click to go to the citizen wall
3. quickly put your mouse over the blue pipe at the agent wall before your at the citizen wall
4. as its loading, it will say "hidden agents location"

i had no idea this is how the agents got to the HQ, until now.
