You might also want to check the Advanced tab on the World Processor. See if OutFile is blank or not. If it isn't, then the map won't be output to the default location.
And rather than remove the textures from use, I'd try to fix them. Should be as simple as correcting a typo.
You know, this has me wondering. Lots of people complain about how the game crashes in the fCon levels. It's always the fCon levels, never anywhere else. The crashes are sporadic in nature, too. Not consistent. I'm thinking that maybe, just maybe, there's a texture actually used by the game that has a mistake. One of the purple textures used on the fCon levels.
And that's why the game only crashes on fCon levels. Because the texture isn't used anywhere else. It's when the player looks at a specific texture on a wall/ceiling/floor in those later levels. The game renders the texture, and at that moment reads the error in that texture. Poof! Game crashes.
The only problem with trying to fix any errors in the textures, is that there's thousands of them. Going through every single one to find any mistakes is a bit of a nightmare.
