so in 16x minecraft with forge 35x your module does not work, after literally arbitering every single mod in my podpack i found that obfuscate does something in which it forgets to properly give an objects meta tag (item player etc). if you made it so it properly inserted all meta information it would work with optifine, until then i wont be using obfuscate cause optifine enables napp premium texture pack and sildurs shaders ultra exreme + volumetric lighting, parralax mapping, and god rays.

send me an email at [email protected] if you feel so compelle when youve fixed this and ill put it back into all the packs i run.
