Tekkit Classic achievement reset

[spiderwalker]

For some weird reason whenever i restart my Tekkit Classic all of my achievements reset and it's very annoying. When I only complete vanilla achievements this doesn't happen,it's only when i complete IC2(IndustrialCraft2) achievements.

Hey, so I had to dig up this fix; none of the known links were working. Download the Minecraft.class file provided by the link, open up the modpack.jar with an archiver, and replace the class file. Happy achieving. http://www.mediafire.com/?q1xhqh68o5eyu1p
