Here is what I did:
On 1.6:
Later, I upgraded to 1.7, now on latest beta.
The bug is the following: Those topic which have this hidden ending, cannot be made “visited” (CSS class). They always show up with dark black as admin. As a normal user it’s OK.
I just noticed this yesterday with unlisted, then re-listed post, too.
Correct, this has always been the case, if the last post in the topic is deleted – whatever it is – then the visited CSS state can’t be applied.
Add a reply to the topic.
So if I don’t want to annoy the users following the topic with an email, my only choice is to close - reopen the topic I guess?
I believe @sam fixed this recently-ish.
Agree I think I fixed this, going to close, flag to reopen if still an issue
