Some textures pack do not respect the "Mipmap levels"

Some pack textures such as legacy pack textures sometimes do not respect the mipmap snow and when you play it and look away you will see that it seems that you put it in 0 Levels mipmap but in reality it is in 4 I do not think it is a mistake this if not rather that the textures can change the mipmap but I put it "error" in case you doubt.
