First off, before I even begin, I want to point out that yes I realize this COULD be IC2's bug, but I wanted to start here to make sure it isn't a forge-related issue that could affect more than just IC2.

 

That being said when I launch my minecraft 1.6.2 with 1.6.2-Forge9.10.0.804 I get a pop-up regarding a block id conflict with IC2...

 

Client> A conflicting block ID has been detected on your IndustrialCraft 2

Client> configuration file. Block IDs cannot be used more than once.

Client>

Client> Block with invalid ID: blockOreCopper

Client> Invalid ID: 349

Client> Already occupied by: block net.minecraftforge.common.MinecraftForge$1@380e4452 (tile.ForgeFiller)

 

I have tried changing this in the config, and the Invalid ID changes with it.  I've narrowed my mods list down to forge and IC2, so I know it's one or the other.  I'm hoping I can get clarification if it's Forge-caused, or if it's IC2-caused or if I'm just an idiot with too much time on his hands.

Quit trying to set the block id to vanilla item id's....

We throw this error when people do that because it's a really bad thing to do. Basically you were just saying that raw fish were copper ore. That's bad.

Stay out of those ids.

I don't have a comment now...

Thank you.
