For example, my previously posted thread, on the subforum page, it says the thread has 3 posts, but when I open the thread, it shows there are only 2 posts (original post + 1 reply).
That is probably because I deleted one of mine, all it had was a full quote of your post, whereas I was trying to quote part of your post so I deleted it.
Ok, that's possible. But I see it on other threads as well, for example, the thread 'Freesound 2 Feedback' shows 21 posts on the subforum page, but in the thread itself, at the bottom, it shows 20 posts. The thread 'Unable to upload' shows 17 posts, but the thread itself is 16 posts.
So that could be due to deleted replies, but then it's still a bug where a number in the database doesn't get updated after a post is deleted.
Anyway, it's a minor bug, I understand most energy goes out to fixing other issues, no problem, take it easy. I understand
