So I am testing with your user and I have not seen posts disappearing yet. That's why I am asking questions. With your follow list, they seem to load just fine. I am trying to understand which posts exactly don't show up so that I can isolate the issue. Do you use the default settings with Tor on? That's how I am testing. Do you have any hidden words in your security filters? When you say "disappearing", do they appear and then disappear or never actually load in the feed? Do they show up in the home feed after you navigate to their profile or not even then?

If this happens again, take a screen shot and send me over, I can then find the even and investigate if it is stuck somewhere.
