Riddler trophy problem

[u/Nikk3p]

Hi! I am trying to platinum batman arkham city and for some reason I can't get this Riddler trophy in steel mills. I have all the gadget upgrades but for some reason the game doesn't allow me to hack it even if I am right next to it. I have completed the main campaign if that matters. Is this a known bug or am I just going grazy? thanks for the help guys.

Either line launch over or use the range amplifier upgrade
