Fenyx same thing is happening to me. Replies arent immediately showing up after hitting post and theres a 3-4 post lost in the void issue. It is resolved after refreshing the page and then will repeat couple minutes later.
For example....@lurchingbeast post the above several minutes ago and its showing it's new and putting a new tag alert
Go to the New Posts Tab, or Whatched threads and see that the last post listed is not the latest in the tread - or go to the main page and it shows the last post in this thread was at 8:32pm last night
