I noticed that the "no longer needed" flagging option for comments was changed to "not relevant". Okay, fine. This should affect all future flags.
But I noticed when looking in my flag history that all of my previous "no longer needed" flags had changed to "not relevant", including those I cast before the wording was changed.
Why was this done? I didn't flag those comments as "not relevant", I flagged them as "no longer needed".
I think (but am not sure) that this also affects currently active "no longer needed" flags cast before the change was made, and moderators reviewing those flags today would see "not relevant" instead. (Thankfully, the display of prior comment flags I made under the original system, such as "obsolete", hasn't changed.)
Is this intentional, or is this a bug?
