What it says on the tin. It appears that with the latest steam workshop update, functionality between Gaslamp's mod loader/publisher and the workshop is now FUBAR. Mods updated/published after the update do not show up in the mod loader or publisher. Subscribing to this workshop item will have no effect, as I belatedly discovered after attempting to update the previous version of RR, going so far as to scrub the mod off the workshop and upload again. Mods uploaded before the workshop update are fine and recognised, but anything updated/uploaded after the change is not listed in the loader/publisher.
