Getting kicked at round end straight to main menu - no disconnect message

Description of Issue

If your Player.log contains lines like:

Playerlog.txt

Server is performing a full round restart. Reconnection time: 25.
Skipped Data message handling because connection is null.
UnityEngine.DebugLogHandler:Internal_Log(LogType, LogOption, String, Object)
UnityEngine.DebugLogHandler:LogFormat(LogType, Object, String, Object[])
UnityEngine.Logger:Log(LogType, Object)
UnityEngine.Debug:LogError(Object)
Mirror.NetworkClient:OnTransportData(ArraySegment`1, Int32)
Mirror.LiteNetLib4Mirror.LiteNetLib4MirrorClient:OnNetworkReceive(NetPeer, NetPacketReader, Byte, DeliveryMethod)
LiteNetLib.NetManager:ProcessEvent(NetEvent)
LiteNetLib.NetManager:PollEvents()

This only shows when a round ends with a full round restart. If you are kicked, you are sent straight to the main menu with no disconnect message.
