Reticles disappear if you're using a custom reticle on newer heroes.

I play mostly older heroes and I've turned my crosshair into a small green box. I noticed that when playing the newer heroes who have custom reticles like Mina and Billy their crosshairs are just gone. The stamina bar is there but everything else is gone. My custom reticle shows up if I disable character specific reticles though.
