[0.12.33][MP] Wrong message on version mismatch

[riking]

When a 0.12.33 client tries to connect to a 0.12.29 "server", the error messages on both sides of the connection are very confusing. The 'client' says:

Couldn't establish network communication with server.

The headless server says:

Code: Select all

   8.035 Info Router.cpp:228: Received malformed packet from 192.168.1.4:34197 (Couldn't read from input file. File could be corrupted.)
   8.524 Info Router.cpp:228: Received malformed packet from 192.168.1.4:34197 (Couldn't read from input file. File could be corrupted.)
   9.026 Info Router.cpp:228: Received malformed packet from 192.168.1.4:34197 (Couldn't read from input file. File could be corrupted.)

Due to the nature of these error messages, I first searched for a network integrity error (the server is ~7 feet away from me physically) before realizing that my Steam client had autoupdated while the server, of course, had not.

Now that the Steam client autoupdates, I think it's probably time for a "version mismatch" error message to be added.

Duplicate. Upgrade your server.
