Apparently some of the people found fixes for their servers, too. They changed from the default game port to another one. (Ex: 25578, 25577, 25576, etc) But some just wait for the next build.
It is an client side problem, and the server has nothing to do with it. If someone gets three bars in 1.2.5, they will only get one bar in 1.3.1. This is the most laggiest Minecraft multiplayer build ever.
If someone has any other fixes for this error, please help.
