This is not really a visible change but fixes certain problems reported in the forum regarding selling worn clothes and the possibility of duplicating items. The inventory now has a central controlling class where most of the functionality is defined. I like to do changes like this. Without a common container that defines the rules like this, the code eventually starts to become a mess when it’s expanded and bugs need to be hunted down. With this new system we now have a little more flexibility and a little more room to expand.
