This started about 10 days ago. I reply to a post, and my reply doesn't show up. If I look at my own profile and check on the posts I've made, the one I can't see in the thread is shown there, but when I click it it takes me to the thread where I again don't see it. Happened just a moment ago in this thread. I should have post #3, but it's not there. When I look at the thread, post #4 follows post #2, and post #4 actually quotes my post (so he saw my post), but I don't see my own post at #3.

Looked at a thread the other day that had 3 replies, but I could only see 2, although the one I couldn't see had been quoted by someone else. In this case it's possible the poster deleted his post, but that still doesn't explain the issue with not seeing my own posts.
