I have a similar issue to #1143 with 1.6.2

My client connects with:

MQ Telemetry Transport Protocol, Connect Command
    Header Flags: 0x10, Message Type: Connect Command
    Msg Len: 64
    Protocol Name Length: 4
    Protocol Name: MQTT
    Version: MQTT v3.1.1 (4)
    Connect Flags: 0xe4, User Name Flag, Password Flag, Will Retain, QoS Level: At most once delivery (Fire and Forget), Will Flag
        1... .... = User Name Flag: Set
        .1.. .... = Password Flag: Set
        ..1. .... = Will Retain: Set
        ...0 0... = QoS Level: At most once delivery (Fire and Forget) (0)
        .... .1.. = Will Flag: Set
        .... ..0. = Clean Session Flag: Not set
        .... ...0 = (Reserved): Not set
    Keep Alive: 60
    Client ID Length: 8
    Client ID: QuinLED4
    Will Topic Length: 15
    Will Topic: QuinLED4/status
    Will Message Length: 1
    Will Message: 0
    User Name Length: 8
    User Name: quinled4
    Password Length: 13
    Password: NotMyPassword

Then I unplug the client device and wait. As expected log shows:

1559035151: Client QuinLED4 has exceeded timeout, disconnecting.

But the LWT is not sent.

Here the full session with one subscriber from mosquitto log:

I think this is the same issue as reported in #1273. If you want to give the fixed version a try, then have a look at the fixes branch.
