keeps throwing a nul value when i try and start a game
Are you using any other mods? Let me know which ones and I'll test them out.
I am using several. Ones that I feel could be an issue is factorissimo 2 and dark matter replicators. And several others such as Bob's and Angel's and pycoal processing.
This mod worked before with all the other things I had installed.
Ok, thanks for the report. I'll give those a try tonight and see if I can reproduce the error.
