Many of my mods are throwing errors on MC launch as they are 'duplicates'.

Shelf mod contains a broken class file. Complain to the author (risugami?)

It the mod_Shelf mod that got an error try a diifrent mod.

[LexManos 1516]

 

Caused by: java.lang.ClassFormatError: Duplicate method name&signature in class file TileEntityShelf

That's a broken mod. Nothing we can do about it.

He has dead code in his mod that breaks the runtime deobf.

Either bitch at the author to remove the dead code, or don't use the mod.

But I get this duplicate error even when using other mods that are confirmed to work. E.g Smart Moving for ModLoader or Forge.

Can you link us to where you found these mods? I tried looking them up based on name, and what I found were mods that weren't designed for Forge.

1 note for you: RISUGAMI'S MODS ARE ALL BROKEN. Trust me, I've tried.
