Sweet... I was just talking with a friend last night about this script needing a pause button. On occasion the script will get itself into an issue with overloading weight. It appears that it would be a result of possible lag or some other hiccup and the script would then act as though it had dropped off its load when it hadn't; therefore, resulting in being overweight because the calculation would be incorrect. This happens so rare that I did not view this as a script issue and have never mentioned it. The only way to clear it up was to stop the script, unload backpack, and reload. I am hoping that the pause button will allow for a simple pause to accomplish this, but in either case it is such a small issue that it won't matter either way to be honest.
I will be sure to test this new version with a Gargoyle using Chiv since that is where I had issue before. I will get back with you.
