I am making a Luigi's Mansion map, and I keep on encountering a problem when I try to play it. In the map selection screen, I do see my map name. But is says luigimansion.bsp. and other map names don't have the .bsp part at the end of their map name in the map selection screen. and when I try to play it says:

SV_SetBrushModel: NULL

Help!!! Anyways I am a new mapper to tell the truth
