Is this a bug or just a flaw in the My comments section?

While the My Comments is nice in a way that I can see people who have commented on my story or liked my story or forum post, it doesn't show if someone has replied to a comment you leave on their story.

This was one of the things that made Lush so special. The camaraderie and authors replying to comments you left. This link is now broken.

Is it a flaw in the design and is on a list of things to be fixed or is this just the way things are now?

Hiya, it's not a bug, just a difference between how the old site was coded and how the new site currently works.

It's a nice feature for exactly the reasons you mentioned, so I'd like to see it be replicated here when time allows.
