Several days ago I noted it stopped working all of a sudden. Running skippy-xd-fix in the console does nothing (no errors either) but skippy-xd seems to work fine. I restored my rc.xml just in case to no avail, meaning the problem lies in the script.
I never touched that part in my rc.xml. If skippy-xd-fix was superseded just let me know. In the meantime, replacing it with skippy-xd did the trick and is working again.
