I voted to close this question as a duplicate of this one. By the time of voting to close, there wasn't any comment linking to that question, and it didn't appear in the "Linked" section.
However, no auto comment was posted:
I added a manual comment later, but can someone please look into what failed in the auto comment process?
Might be relevant, that I have a support gold badge, but the hammer (aka, using the gold badge to close on my own) wasn't used since I put that tag myself prior to closing. I am 100% sure this didn't stop automatic comments before though.
