✅ Threads no longer showing "NEW" tag on activity, "Response To:" widget missing

In the last day or two, I've noticed that forum views no longer show the "NEW" tag when a thread has had new posts since you last visited it, which makes it hard to follow new activity. Also, responses to posts no longer show the "Response To:" widget, which makes it so hard to follow a conversation in flat/chronological view that the mode is almost useless.

This is occurring across browsers and sessions. I'm guessing it's a bug - any word on if/when it'll be looked at?
