From what I can see, it's a problem involving ghasts and minechem, but I'm not sure how that would happen.

I'm running 1.6.4 with java 1.7.0_45 and no idea what version of forge (I'm using the technic barebones pack as a basis, and it doesn't tell you). Any help would be great!

 

There is a mod list here
