Something weird happened as I was handling an auto-flag (more than 20 comments on answer) earlier today:
I clicked Move comments to chat and okayed the prompt to also delete the comments, and then moved on with my life and ordered my McDonald's.
Then a fellow moderator ping'd me in chat to let me know that the comments were still there. I figured it could have been a mobile hiccup (did it from my mobile browser after all), so I went back to the post and saw that the 20-some comments were indeed still under the flagged answer (the flag hadn't been cleared?!), so I clicked that Move comments to chat button again (this time from a desktop browser), and got this message:
The comment/link to the chatroom had been added, but the comments lingered under the post, and the only way to actually clear the flag was to click No action needed... and dismiss the flag as useful.
I swear I've seen this actually work before (i.e. "move comments to chat" actually moves the comments to chat), so what happened?
Can we improve the Move Comments to Chat functionality? is status-completed, so if the intent was to actually improve that flag handling tool, then it should behave the same way as the mod menu option, and it doesn't.
