Fandyllic, it is not due to lack of MediaWiki expertise. I'm sure you did not mean to present that assumption as fact.

It is due to the Forums code being specifically designed for an outdated codebase and not being viable for the newer codebase, much like compatibility issues with games designed for older versions of Windows not working on Windows 10.
