I was trying to use the spectral eye amulet but I don't get an outline surrounding any entities. I initially thought it wasn't working altogether, but in third person I can clearly see the effect on me. I'm not using shaders/optifine. I'm using in my modpack Age of Fate. Thanks for any help.

Same with me.playing on medieval minecraft v46 forge 1.16

1.16 is no longer supported. If this still happens in 1.18.2 please open a new issue.
