Hello, I seem to be having a problem with my custom achievement page. I looked on another post that had exactly the same crash and was resolved by initializing the achievements in Init  and registering the page in PostInit. Unfortunately that did not resolve my crash and still gets the same error. Link to that post: http://www.minecraftforge.net/forum/index.php?topic=16909.0

 

Here is my code

 

Mod Class

    @EventHandler
    public void load(FMLInitializationEvent event) {
FurnitureAchievements.loadAchievements();
    }

    @EventHandler
    public void postInit(FMLPostInitializationEvent event) {
FurnitureAchievements.registerPage();
    }

Hopefully you can point out where I am going wrong. I am sure I had it working before or I wouldn't have released the mod to the public already.

 

Thank you,
