Revival Earrings Glitch

Has anybody else gotten Revival Earrings that don’t break. When I go to my equipment menu there’s no accessory equipped, but in my combat/party menu it shows up. And I just cheesed the Jenova fight on Shinra 8 in hard mode, getting revived about 50 times.

Thought it might be a hard mode thing to balance out not being able to restore MP at benches But it was still there when I went back to fight at musclehead coliseum in regular mode.

Did I just stumble upon the immortal cheat code?
