While working on a test map i noticed that changes suddenly weren't, for lack of a better word, applying when i compiled. Compiles throw no errors and .bsp in the maps dir shows an updated date modified each time i compile, but alas none of my changes appear, it's as if l4d is loading an older version somehow, any help appreciated, thanks.
