Further Information

After instaling and deleting Mystical World, Blood Magic and Astral Sorcery mods, the Lexica Botania appears with the missing texture. I thought it can be an incompatibility with some mod and after deleting Optifine it returns to the normal texture. The Optifine version is HD_U_G8.

I tried to re-install al the mods, the whole .minecraft and the bug persist. Mentioned the three mods because before installing them the book seems to be normal.

What I expected to happen: See the normal texture of the book.

What happened instead: The texture is missing.

yes. Unfortunately, we can't fix it as we have no idea what Optifine does.
