Okay, so I have been having problems with joining servers that have multiple lobbies, e.g. Mineplex. This problem started just today, when I got Minecraft FML 1.8. Every time I tried to join it said "Kicked whilst connecting to lobby-# If you wish to use IP Forwarding, please enable it in your BungeeCord config as well!. I looked on my game output, and it kept repeating Unexpected packet during modded negotiation - assuming vanilla or keepalives : net.minecraft.network.play.server.S40PacketDisconnect every time I connect. I removed my mods, and it still said that! This only seems to happen when I use FML. PLEASE HELP ME
