Romulan mystery: Coliseum special weapon rack

kursed

The original walkthrough says in order to get to the weapon rack behind the forcefields you need to come back to the rack later ,well there are no longer forcfields in the game and it seems to be random when the rack is avalible for interaction. Does anybody know how to get this to work now i'm trying to get the Nausican Tegolar sword. https://sto.gamepedia.com/Nausicaan_Tegolar_Sword for a friend.
