New replies not showing

[Smoker]

I keep a bookmark to 'My Activity' so that my first port of call, when coming to FOH can be to see if there are any new replies to threads I have posted in.  Ok, that sounds a bit self-centered hahaha, but it's useful to see that if you're trying to arrange a meet, or waiting for some advice from members.  So, in the past, threads would show up in bold if there were new replies, and I think there would be a red star if there were new replies AND I had started the thread.  Now I don't seem to have that any more.  Sometimes new replies are shown, and sometimes not.  So I have to go to each individual thread I have posted in, and check them manually.  Is anyone else having this problem?
