Thanks, I'll fix this as is shown below.

I do have a question though, it is honestly really that much easier to
revert a whole days worth of changes (and therefore not get the code
tested at all) than to simply add the obvious one liner?

It seems to me to be absolutely the wrong tradeoff in these situations.
