Tekkit Classic Achievements Fix?

[usernameOS]

This is a pretty common bug whose effects are:

- Achievements reset every time you close a world. When you re-enter a world you will get the Inventory Management Achievements(AKA Pressing E).

The only solutions I found where from years ago, one referencing a technicpack forum thread that doesn't exist anymore, and the other a now-dead MediaFire link.

Most of the responses to people asking this question where boiler-plate responses like:"Did you install mods?", "Did you mess with the jar?", "Did you update?".

Any solutions?

Hello from 2022!

The original bug had to do with Minecraft verifying the achievements file at startup before the various mods tell the game that they have achievements, too. So Minecraft thinks the achievements file is corrupt and tosses it. A forumgoer by the name of gotyaoi originally posted a fix in 2012. While the tekkit forums no longer exist, that particular post was archived by the Internet Archive and can be viewed here:

The file itself was posted to Mediafire and that link is still live:
