Not clear, so resolving.

Please provide better issue messages and re-raising one that people can actually take actions at?

General advice:

• Get the parameters of the failed test. AFAIK every programming language here at CodeWars has some way to print something.
• Get your result.
• Re-read the kata's description. There are a lot of issues where the user missed something in the description.
• Check your result manually (if possible). There are quite a few issues where the user's result was just wrong.
• Check that kata's discourse section if this issue has already been reported.
• Add a comment.
  • State your programming language and version as shown at the top of the page.
  • State the parameters of the failed test, your result and the expected result (if available).
  • Add your solution code surrounded by a line with just three backticks (```) and mark the comment as "having spoiler content".
  • Label the comment as "Issue".
• Give the author a few days to respond.

Luckily, the test cases are randomized, so I was able to pass it through. I guess if you are getting just one wrong, try to submit again and it should work.

I am also pretty sure I have the correct answer, but it's not passing me through :(

Are you certain that the test cases are correct? My solution is correct for every range or single year that I've tried, but when I submit my solution it says the value doesn't match the expected value.
