On the Home Cooking Community I scrolled down until the page loaded more posts, viewed one of these posts, then used the back button to return to the community main page.
The top post now listed on the Community page was no longer the most recent post. Instead it was the first post to be loaded after the three dots loading icon. I had to click on the Chowhound icon then re-enter the Home Cooking community.
I tested this several times by scrolling down past the loading icon and the same thing happened each time.

The screen shots show the most current post at the time, and the page as it was shown after clicking the back button.
