Mapping Problem

When i render and run my TF2 map, instead of loading my current map, it loads an earlier saved version of my map. I have already tried saving my map to a different name and deleting the old save files. Something i think is causing the problem (that started when i started having problems) is the following (taken from the map compiling console of hammer):

WARNING: BSP node with unbounded volume (material: <NO BRUSH>, near (-16392.000000, 16392.000000, 16400.000000))
WARNING: BSP node with unbounded volume (material: <NO BRUSH>, near (-16392.000000, 16392.000000, 16400.000000))

....And goes on like that for a few hundred times

Any ideas?

Try going to the co-ordinates given, see if there's anything strange you can spot. If there's any odd brushwork, try deleting the brush, saving the map as a different name, and compile.

Hope it helps.

well, the thing is, it always worked before. i also dont want to find literally 250 different coordinates. Any other way?

Most of those co-ordinates are outside the limits of hammers grid. I sure that clipping at odd angles, or carving weird shapes made this happen with hl1 mapping, but I've not seen it with hl2 before.
If you don't have anything obviously sticking out of the main grid limits, try copy/pasting everything into a new file. That sometimes gets rid of phantom brush errors.

i tried copying everything/pasting into a new file. No luck though, but thanks for the comment. Any other ideas?
