The full story is, I approached Zipper593 and ZoZo (both BI staff) about fixes to A2 files ported to A3. This is one example. I said that I would go through the rest of the files on the Module Improvement Project (https://dev-heaven.net/projects/mip) at a later date, and submit additional fixes once confirmed they are still relevant.

The fixes are stated above and affect mostly debug and custom locations.
