TR Posts being swallowed?

I noticed that the thread “New York most polite city” has a post count of 30 (as 1:55pm CST) https://www.techrepublic.com.com/5208-6230-0.html?forumID=8&threadID=196510&start=0

But there are only 17 of them being displayed. I knew for fact that two posts that I read earlier are gone.

Is the system experiencing any problem 🙂 ?
