Not sure where else to put this, the IC2 forums are really difficult to navigate. I made my own 1.6.4 modpack to play on a server with around 15 friends. I've installed IC2 Experiments and Gregtech. We cannot smelt sticky resin into rubber. We can extract it, we can centrifuge it, but we can't smelt it. Is there any way to fix this? I've searched through configs for about an hour, and haven't found anything to fix it.
