So, fun fact. On the Thermal Expansion wiki (http://thermalexpansion.wikispaces.com/) there is an issue tracker. You will notice that NOBODY HAS REPORTED THIS. So, it's not a nerf, it's a bug. The sky isn't falling and I'm human. Sorry about that.
If one of you would report stuff like this in the future, that'd be great, thanks.
Sorry King Lemming!!! I didn't realize it was a bug. I thought it was a balance thing. To me a bug is usually something that crashes the game or makes something not work. This didn't do either of those, just changed output values. I figured since it worked fine, that this was the new norm. My error.
