I'd be happy to do so, but it is a pretty low priority item at this point. The thing that takes the longest is simply going through the table and finiding which did or didn't change. If you wanted to point those out, I'd be much more likely to be able to resolve sooner rather then later. Thanks!

Here's the actual code table:

Code:
