Invultri, you should do these config changes as soon as you can:
IC² cfg
"generator = 0
geothermal = 0
semiFluidOil = 0
semiFluidFuel = 0
semiFluidBiomass = 0
semiFluidBioethanol = 0"
It seems that latest GT re-enabled IC² generators.
@greg: force change these settings on IC² config if GT is installed, if possible. Thus you disable the usage of them, but still keep them as basic crafting items?
