I've recently encountered a situation where a thread appears on the Forum with a green dot indicating there is a new post. But there is no new post. In fact, it positions me at one of my posts in the middle of the thread.
I'm finding this happening on the same two threads. And I've noticed that those threads have posts indented. I don't know if the indenting is new or I never noticed it before.
I scroll to the bottom and click on the "All Threads" link. The green dot is gone. But it comes back. So I've tried, when I go back to the list and the dot is gray, clicking the gray dot. It turns green. Then I click on the green dot to turn it to gray. Some time later it's green again with the incorrect positioning and no new post.
It's really annoying.
