It worked fine for most of us and I don't think that it has been tweaked.
Perhaps you have this or a similar issue related to custom FH maps or S&T packs, causing a game crash to desktop, for which there is a known solution/workaround:
A reminder to eYe and RADIOSMERSH:
I think it should also be added to the installation guide, or possibly even the FHSW installer
Or if you get a sudden "Disconnected from server" at the end of the loading or after loading the map, it may be another bug affecting only some maps. You just need to try reconnecting a few times and in the end it stops disconnecting you.
