This comment on the Star Wars question Did Darth Vader ever operate a button on the devices on his belt or his chest? reads:
If canon isn't an issue for an answer, you should add the star-wars-legends tag
A couple of hours ago the OP must have seen this comment and added the tag. On seeing the edit, I opened up the question and saw the now obsolete comment and so I flagged it as "No longer needed". To my surprise this flag was declined with no message.
I proceeded to re-flag it with a custom reason assuming it was either a mistake on the mods' behalf or I was completely overlooking something.
The question has the Legends tag added by the OP therefore a comment saying you should add it is no longer needed. (flagging again with an explanation as the last flag was declined, don't know why).
Again to my surprise it was declined and again it was declined with no message leaving me completely in the dark as to why it was declined.
Now, as far as I can tell a comment about adding a tag becomes obsolete once the tag has already been added so I can't work out why my flags were declined and the comment not deleted.
Why were my flags declined?
