[SOLVED]Is this an ID mismatch?

    I tried to run IC2, IC2ComboArmors, IC2 Nuclear Control, Buildcraft and Traincraft.

    Is this a typical Block_ID mismatch or something 'bigger'?

    When you see

    Code
    java.lang.illegalArgumentException: Slot xxxx is already occupied by yyyyyyyyyyyyyy when adding zzzzzzzzzzzzzzp


    then you should known it is a Block ID mismatch.

    ^Not exactly. There is one, but it doesn't save the IDs into the configs, so you have to go through it each time MC starts up.
    On the other hand, there are some mods with Dynamic Allocation in their configs, which allow the mod to search for free IDs and then set the configs to it. For example, IC2:

    Quote

    # Enable searching for free block ids, will get disabled after the next successful load
    B:enableDynamicIdAllocation=false
