What I'm currently doing is going through all official maps that don't have a .NAV file and using "sv_cheats 1; nav_generate" to generate navmeshes for them. One of the admins on my server runs an event called Horsemann Hell, involving spawning the Horsemann on an official map and letting players kill him. Not sure what else he does with the event as I've never been on when he does it. So my question is about those .nav files I've generated. Do I just drop them into the gameserver's tf/maps directory or do I also have to BZIP them and upload them to my server's FastDL as well as dropping un-BZIP'd versions into the gameserver's tf/maps?
