Somehow the Texturepack 1.10 has a bug… Everywhere where tall grass should be "Steve Klone"
Have tried it with version 1.9, because the grass looks pixelated and with version 1.11 everything is totally blocked
I use Minecraft 1.10
Texturepack LBPR Reload 1.10
OptiFine_1.10_HD_U_E7
Forge 1.10
If the normal grass texture does not bother you, simply delete the file for tall grass
