YEAH, erm, forge suddenly started doing this in eclipse? Why, can it be fixed. I've tried reinstalling Java, and deleting and reinstalled forge. One thing, I have another workspace, it works fine. It's only this one, even though they're on the same version, and they both are clean installs WTF Forge??
