Crash occurs when disconnecting and connecting to a server without quitting

[LemonHaze420]

To reproduce this crash:-

1) Connect to a server
2) Press F7 to disconnect, or end the server process or cause any other network disruption which would lead to an eventual timeout.
3) Attempt to connect to a server (does not have to be the same server)

This issue may linger, although the solution isn't necessarily trivial at this point in time.

Issue seems to only be present when the client was spawned via the browser integration.

Tested multiple times with a single client disconnecting and reconnecting - with no issues.
