I think it's because the map is so spread out. It's not big, really; it's just spread out, if that makes sense. Eventually I got it to compile. I tried compiling at different points in the map and eventually got it to work. I made some changes and now I'm having trouble finding that spot, again. I got that disabled, but it's still not working.

That so sounds like you need to disable radius culling like i told you. It is the red circle with the R in it in the upper toolbar. Shortkey for that is 'c'. The radius culling does not draw elements in hammer that are a certain distance away. These objects will not be compiled when Radius Culling is enabled.
