Maybe the tutorial which includes the model was released first before the other one and the creators think you´ve downloaded the old one before...
Nope, that's not it. Game Design Tutorial 2 (which is where cbabe.mdl is located) was uploaded in May 2007, while the FPS tutorial part 1 was uploaded 11/14/2004.
ps: the "famous" office level is NOT included into Gamestudio 6 or 7 if you wan to do the old tuts with the office level you´ve got to download a5 or maybe an old AUM
Haven't heard of this. Probably in one of the tutorials that I haven't come across yet. But I'll keep an open eye on this one.
