When I opened Entity framework large data set, out of memory exception ( on Windows 10 laptop with Chrome browser), the page shows "3 Answers", but actually only 1 answer is visible. I am 10K+ user and I am logged in, so I should see deleted answers (one of them is my old answer) I am able to see the same page on iPad's Safari with all 3 answers visible.
Similarly ASP.Net raises error "System.InvalidOperationException: Collection was modified;" when switching to Vietnamese shows that it has "1 Answer", but no answers are visible. Again, on iPad I can see one deleted answer.
The problem is similar to Wrong count of answers in question, but explanation about sync daily job is not applicable for me, as all related answers were deleted a long time ago, and the issue with the second example I've noticed many days ago(and still able to reproduce).
