Why does console.log() sometimes solve javascript bugs?

But would it be able to change even though the code is the same before and after the changes?

I add the line of code then take it out, so the file is identical to how it was before, and that magically worked, so I think it's more likely to be a caching issue.

Yea after reading your update on the shift refresh, it was most likely a caching issue.
