I'm also having troubles, cartographer not being skinned any clue what's conflicting ?
After some experimentation found out the cartographer module LooknFeel is causing the conflict. This error has nothing to do w/ skinner, if you disable the module you can see that skinner is actually working. Also, if you disable the LooknFeel module you'll have to disable Hotspot as it is dependent on LooknFeel.
Oh and Hi, long time lurker here, first time posting :)
