I have folders of previous versions of the game and these have the normal menu screen when startup. I tried to open with internet disconnected and nothing, comes out the unicorn. I checked the recent changes in the registry and nothing, as usual. I checked with Spybot, SuperAntiSpyware, Nod32 (in my Laptop), Kaspersky Internet Security 2010, Malwarebytes and my whole arsenal available and nothing, I have not had any intrusion on my pc or rootkits or viruses or spy or anything. Of this I am sure that my pc has not entered anything malicious in the past year and a half since I learned the quasi perfect protective configuration of my computer. It would not be the first time someone angry with a game or its creators believe any virus that affects only the folders with the exact name of the game and so laughs at them. But my tools tell me that everything is exactly the same as yesterday, including the Windows registry. I watched the game files that control of the menus and music and they are exactly the same, by comparison with WinMerge. I also checked my files in documents and settings and My documents relating to the game and I think they are exactly the same.
Unless I've missed something, everything makes me think it's a joke in the patch 1.22.2 (the only version of the mod for now on my pc has been affected )

Really the only thing I can think of is that every time you start the mod like us to
EDIT: Confirmed? that was simple to check. Only by changing the date of my pc to 1 March the menu screen is the same as always.
