Topics [Design and Customizations] in my notifications aren't appeared in the forums. I could access the topic through the notifications but not in the forums.

I even try to search them up with exact titles but every single one of them comes out 0 results.

It's been almost a week and there's more "new topics" by the day not being shown unless you view them through notifications.

This is due to them being in a forum you cannot see. I will get someone to take a look at why you are getting notifications for these. Its just the forum is named the same
