The names of white, black, blue, and brown dye are mislabeled as Bone Meal, Ink Sac, Lapis lazuli, and Cocoa Beans, respectively. The original items are still present. I have no resource packs and my language is set to English (United States). It appears that the name of each dye has been recently reverted in the language files.
