It's not a bug, Gregtech replaces the mass fabricator with the matter fabricator, it's intended to do this. Although you can change this in the server config so that the mass fabricator is not replaced I would ask people to refrain from doing this and try the FTB mod pack as it's meant to be played
Seriously, this horse has been beaten to death in like 20 other threads, let's cut another bludgeoning session short and agree to disagree on this, at least in this thread. If you want to make some glue from the poor horse's carcass, the best thread with the audience most willing to engage is probably this one now.I see a problem with this argument... what about playing the mods as the creators meant them to be played?
Thanks.
