Info observer point

[Haggis]

I have installed 3 of these in my map,when it is compiled the 3 points work fine but when i put it on my dedicated server i know i am going between the 3 points but the screen is black,anyone know what the problem is.Fixed it,what you have to do is change mp_fadetoblack 1 to mp_fadetoblack 0 in your server .cfg
