Crash Trying to fix an issue with our modpack

[SinisterPixel]

We're trying to run a custom modpack. I've assembled it, resolved ID conflicts, and as far as I can tell have done everything correct but I'm having an issue with it.

 

Upon trying to generate a world, the game will close out. Checking the crash report gives me the following:

Any ideas?

Providing a link to your pack page or download would help diagnose problems. That being said, how much memory does your PC have?

Probably worth noting that ID conflicts were resolved using idfixminus which is no longer in that pack.

 

I have 4GB (2x2) of DDR3 RAM.

• You are using an old version of Forge. This is usually bad. I think you have 953 and you want 965.
• You have an amazingly old version of IronChests.

Fixing those two concerns allowed me to make a SSP map using both Default and Biomes O' Plenty map type.

Thank you. The problem is resolved.
