The server is back up. You will need to update your client. Sorry for the downtime. We ran into some issues that we still haven't quite fully tracked down. The recipe issues that came up in the last update should no longer be an issue. We've also added GammaBright, MouseTweaks, and a mod to make ships out of blocks.
And so the bloat grows, with GregTech at its core; always hungry for more RAM and CPU power. I kinda wish sk still had his old PC.
Don't worry, Vincent will be back. It's just called the "ships" mod. Not airships or anything, just boats
You probably need to go to the launcher's options and then manually set the path to Java. It might be using some 32-bit version of Java that you have on your computer.
