I can confirm this will happen on a stone silver vanilla client.

I know I am not the Reporter, but I have experienced this issue. I know for a fact that it is a latency issue, but in 1.2, Minecraft would warp you back to your actual location and would not stop until the latency went away enough for you to move. This is different behavior, you completely lose contact with your server character and may "free roam" with your client character. I want Minecraft to have ways to fix this when it happens. If we warp back all of the time, sobeit, we are still connected to our server characters.

This bug is very irritating to me. It happens all the time, so much that I can't really play Minecraft anymore on SMP.
This is a big problem, synchronization issues. This used to not be a problem, because in 1.2, the client changed the position of the client's character to the server character every second. This is why you would sometimes not be able to move in 1.2, you did de-sync, but because of the constant warping, you would, after a few seconds, re-sync. This warping behavior appears to have been removed in 1.3, which creates this problem.

Please spend a little bit of time to detect and resolve de-synchronization, it is very annoying.
