I just saw a new error when handling a re-flag. The sequence here was:
Post was flagged by non-staff
A moderator (not me) approved the flag and hid the post
The OP made a no-op edit that did not resolve the flag (literally nothing was changed!). The post was automatically un-hidden
Post was flagged by non-staff again
I (a mod/admin) approved the re-flag and chose to hide the post
Post was not hidden.
When I (the mod/admin) try to flag the post again I now get “An error occurred: Thanks, but we’ve already reviewed that post and determined it does not need to be flagged again.”
The post is hidden/grayed out in the UI after dismissing that modal, but upon refresh it’s not hidden
I’d really prefer to use standard moderation tools (and not straight post deletion).
