I get the following error when I start minecraft
java.lang.NullPointerException
Crash Log:
Without reading your code, you're trying to access an object that points nowhere.
Example:
[1] integer x;
[2] x = new integer (2);
If you would already use "x" after line 1, you will receive a null pointer exception. Check the line in which your problem occurs and where the variable is assigned the reference to an object. Should be understood relatively quickly.
Can you please read the code and tell me what mod causes errors?
Looks like thaumcraft
As it looks, Thaumcraft tries to add a biomome and fails because an object is missing.
See answer from xxxcyberxxx
Okay, unfortunately thaumcraft is important for the project do you have any idea to fix that?

Either you rewrite the code or you are looking for an alternative version of Thaumcraft, is the modpack itself put together?
