It worked little time ago, I have undone all changes and it still crashed.

It was also not registering 3 of my blocks although they were registered like all the others and it told me:

...This means the object wasn't registered. It's likely just mod options.

 

We won't be able to help much without seeing your code. However, it looks like you have a NullPointerException here:

meaning something wasn't initialized.

Post your code. We're pretty telepathetic here.

omg I'm so stupid, sorry guys!

I didn't even register the block, just the block item!
