No [x#] Message stacking

In the new minecraft, whenever anything is said/commanded in chat, it stacks.
How do I make it so this doesn't happen? It makes my plugin useless....
Example:
Old:
[player] Hi
[player] Hi
[broadcast] Hey
[broadcast] Hey
[broadcast] Hey
Now:
[player] Hi [x1]
[broadcast] Hey [x2]

Oh wait this is only nodus. . . Nevermind>.< Anyone know a better client that lets you log in multiple times?
