I've been doing it all day, trying out iterations of my map. Then, I PAKRAT some custom textures into my BSP. I rename the folder in which they are on my drive (to force the game into using those in the BSP) I load up TF2, then type "map " (with the space after) in the console to see the list of maps and pickup my map to play.... hl2.exe crash! I tried to rename back my custom materials folder, I quit steam.. I even restarted my computer. It still crashes when I type map in the console. I know when you type map it makes the game refresh the list of maps, but I don't know if there's a file somewhere that's created or updated when you do so and maybe got corrupted and needs to be deleted. Any help appreciated. Thanks.
