Do you realise something weird about YA!M lately ?

If you try refreshing the screen in a question, you will see TDs appear and disappear then reappear again on and off. Also the same for TUs.. first I saw 2 TUs then 1 TU then 2 TUs then 0 TUs again and again for the same answer as I keep refreshing the screens. Finally when I go in again a few hours later, there were totally no TDs just 1 TU each for the answers... weird. Have you faced this lately ? What's happening ?
