Hahaha, oops. Um, I guess -nodetail doesn't do what I thought it did. I thought it removed the detail flag, but it actually removes the detail brushes entirely. So, yeah... I load it up, and I'm like, "Um... half the map is gone." No stairs, no lights, etc. I'll be compiling it again tonight without that parameter set. Also, there are a few areas marked as detail that shouldn't be, like in that tunnel, there are some big holes in the floor. Don't know how much of a difference that makes.
