I fixed it myself, but only because SanAndreasP gave me a push in the right direction.
This video explained what I had to do.
I read through a lot of bug reports and I must say that I'm disappointed in your behaviour Lex. You have the opportunity to help people, yet you act like an ignorant blind prick who just answer to answer, not really to help.
Once again thanks SanAndreasP, I can now build a Diamond Generator and other things will follow soon after!
