IC2 causes hang in custom modpack - no crash

    Hello everyone. A friend and I are trying to set up a custom modpack. Using the following mods:

    Display Spoiler


    Ars Magicka 2
    Binnie-Mods
    Biomes O' Plenty
    Buildcraft
    Additional Buildcraft Objects
    Ender IO
    Forestry
    Evoc
    InfiniBows
    Inventory Tweaks
    PowerSuits
    Power Crystals
    Rail Craft
    Rotary Craft
    Applied Energistics
    Automic Science
    Auto Utils
    BiblioCraft
    Chicken Chunks
    Chisel
    Death Counter
    Ender Storage
    Hardcore Ender Expansion
    IC2
    ICBM
    Iron Chest
    JABBA
    Logistics Pipes
    Mad Science
    Magic Bees
    Micro Blocks
    Minechem
    Modular Force Field System
    Natura
    NEI + NEIAddons
    Opis
    QuantumCraft
    QuarryPlus
    Revamp
    StevesCarts
    Switches
    Tinker's Construct
    Thaumcraft
    Thaumcraft Extras
    Thaumic Tinkerer
    TMechworks
    TorchLevers
    Translocator
    Universal Electricity
    Waila
    Witchery


    The modpack works great without IC2 included. As soon as it is added, minecraft hangs at the mojang screen. There is no crash and therefore no crash report unfortunately. I've heard that binnie mods can cause problems but removing that didn't fix it.

    I've also tried turning on IC2 dynamic id allocation but that doesn't change anything.

    The last thing in the logs are a bunch of lines similar to

    Code
    [SEVERE] [ForgeModLoader] Found anonymous item of class icbm.core.prefab.item.ItemICBMBase with ID 31997 owned by mod ICBM, this item will NOT survive a 1.7 upgrade!

    Mods that receive this severe warning are ICBM, Rotary Craft, Magic Bees, Forge Microblock, Thaumic Tiknerer, Ars Magica 2, QuarryPlus, Quantum Craft, Minechem, Railcraft, Tinker's construct, and AtomicScience.

    It is doubtful that those warnings are causing mc to hang since they are there whether or not IC2 is added.

    If anyone has a solution or ideas, I'd love to try them out. Thanks for your time!

    No I actually meant waiting longer on startup..It fooled me at first too that the startup was so long. Now I am just waiting from the results of OP adding each mod at one time.
