/slaps TPG.... No, the chances are its a far more fatal problem than that. The game loading an older map is usually caused by VBSP crashing and the compiler picking up the previous version, so you've got some issue making VBSP to crash most likely.
Post your compile log through
www.interlopers.com/errors then check things like are any displacements func_details since they can't be both and that is one of the things that may cause this.
If you're still having problems, read your log yourself (interlopers can't catch everything) and if that doesn't present an obvious fix, report back.
