Hi Sol-pancakes, congrats on a successful new community! I'm Garth and I'm part of the team that develops the Discussion feature here at Fandom. Lakewood Academy High School turned up while I was looking at new, active Discussions and this one was at the top. Particularly impressive is the first post with over 17,000 replies!
So, I was also surprised to see this post disappear a few days ago. The issue seems to only affect admins (log out and take a look) because of the extra moderation options admins see in the post list. I wanted to let you know we're working on a fix for it.
In the meantime, you can continue using the Following tab as you suggested previously.
