Support Request: Lag spike after checking Nuclear Reactor

    In my Superflat world, I have a Nuclear Reactor. But, when I check it to see how it's doing, I get a massive lag spike (5 FPS) and I have to reload Minecraft to remove it. But something's very weird - if the reactor performs the bug where no sound is playing, I don't get the lag. It seems pretty weird.


    I'm using
    The latest 1.2.5 version of Modloader
    The 3.1.3.105 version of Forge
    With the following IC2 plugins:
    Modular Force Field System
    Compact Solars
    Advanced Machines


    I would be very thankful if someone can help me out. ^^
