I was playing on the multiplayer server mc.hypixel.net, and I disconnected and joined the server mcplayhd.net. When I logged in to mcplayhd.net, the chat was showing mc.hypixel.net messages, even though I was not connected to mc.hypixel.net.

What I expected to happen was...:
The chat messages to be sent by mcplayhd.net

What actually happened was...:
The chat message were being sent by mc.hypixel.net

1. Join a multiplayer server.
2. Disconnect quickly
3. Quickly join another multiplayer server.
