After today's Dev update (ver 1.37.128466) the Dedicated Server requires Steam account in order for clients to be able to connect to it.
If Steam is off line, the dedicated server executable launches the application but only two lines are printing. The third line with the port number and the steam Query is missing.
Any client trying to connect, are rejected.
If the Steam account is on, then everything is normal as before.
This has started happening with Dev version 1.37.128466 (today's update)
