I have no idea if it's a bug, or if I did something wrong, but my SWRG wont let me fly anymore. Whenever I press C to activate the forcefield, that doesn't work either and the activation sound plays nonstop. Still protects from fall damage though. Even reinstalling Tekkit and making a new world had no effect. Help? D:
Oh, and this is on a single player world.
EDIT: It stopped working while I was in mid flight and using a philospher's stone to craft some waterproof gold pipes if that helps at all.
