Pretty much everyone that logged onto Regrowth today encountered an error with Aquatweaks. This prevented them from logging into the server, but the solution to this is very simple. To those who don't know how to fix it, go to this folder: Regrowth\minecraft\mods, and take out the Aquatweaks jar file from the folder and put it on your desktop or somewhere else. Then you can run ftb again and it will be fine.
