So I was on SMP9 earlier when I went to type a message to a friend. I hit ENTER and the message did not appear on my screen. I tryed relogging in, but now I cant type anything, mobs in the wild don't react to me, and chunks aren't loading. I don't get messages from anybody, and nothing is shown in chat but the Welcom message. I tried logging in again, restarting Minecraft, and restarting my computer. My internet is working fine. Please help!EDIT: On other EMC Servers I just spawn in the Void, and still cant use chat or commands.
