A lot of the time when i post a reply, it will show after i press Submit (due to the ajax) but if i go to User CP then back to that thread, it wont be there. However it shows that the most recent poster was me, and there is an increase in replies, but my thread isn't there.

It take about me about 5 times (of loading the page) to actually see my post there. I am not a new member so my post should show up immediately all the time... unless i am under moderation for some reason...
