Tekkit Null Pointer Exception upon block place

    Right, so. I just started using Tekkit on my server and so far I'm enjoying it immensely. I finally got a chance to craft a generator, only to try and place it when *bang*, null pointer was thrown on the server and my client disconnects.

    I tried looking at this thread: https://forum.industrial-craft.net/index.php?page…d&threadID=4917 but my problem doesn't quite match his, since all the mods load in fine.

    I checked to make sure the block IDs on both the client and server matched, and I looked at ModLoader.txt, but there were no evident errors within that file at the time of the exception.

    Can you guys please help me out? This is getting to be a real pain and I don't really feel like starting over with just Bukkit.

    I am using all the default mods included in Tekkit's server pack, as well as some plugins.

    Plugins:

    Thanks for your time and if I find a fix I will post it here!

    Shouldn't be, let me double check the IP.

    Edit: My bad, last number is 171 not 170

    I opened up the BlockMultiID class, and on line 145 it simply says "dup", with a value of 150. What I take that to mean is that there is a duplicate block conflict with some other mod, which I will check now.

    Thats ok Harry, it's fixed now.


    Thank you very much Catt. Could you please link me to the thread you mentioned? Everything is working now and if that thread helped I want to double check any other plugins I might want that would break this.
