I've been going over the rig to correct things I broke updating the installation method...I think I've found most of them. I won't really know for sure until I do a complete installation and that will be the last part of the process. I've done some tweaking to Squetchy Sam's modeling, so that I can better see a few things in the shoulder...which led me to tweaking the entire torso, forearms, legs and feet. That means I'm re-rigging a few things on him before I get to finishing the shoulder update...which is about half done at the moment.
Here's a quick image showing the tweaks to Sam (there may be a few more when it's all done).
