I wanted to nerd out, but to be sure i checked every thing i thought of. I remember that hunger was introduced in beta 1.8, but, as it turns out, so were glass panes, experience, and the new porkchop texture. And the softer cobblestone texture was introduced in beta 1.7
Frustrated, i examined the image closer and spotted some gravel in the distance with the texture that came way after beta 1.8
I concede that i wouldn't have noticed it, but it's not impossible >:]
