Support Request: game crash

  • I created a new world, had no problems playing with multiple mods installed including IC2 until I tried to create machines for IC2. After I created the extractor and placed it, I then attempted to right click on the machine, which crashed the game. I tried going into the world again but the game crashed as it tried to open the world. Subsequent attampts yielded the same effect. I've tried to open other world but they have worked. Could anyone help me out with the problem?
    I've read that it might be mod loader but I dont recount ever installing it and the version im playing on is over 1.8. Im running minecraft 1.7.2 and 2.1.4 of IC2.


    First crash:

    Ive posted the error report for the first crash(the one with right clicking the machine) but not the others because of the character limit. Would it be helpful if I added it in as well?
    Any help would be welcome. Thanks!

    Not sure why you'd want to stick with 1.7.2, but that crash looks a lot like you're missing the ejml library IC2's meant to download when it first starts.

    145 Mods isn't too many. 9 types of copper and 8 types of tin aren't too many. 3 types of coffee though?

    I know that you believe that you understood what you think I said, but I am not sure you realise that what you read was not what I meant.

    I see this too much.
