First of all, hello everybody! : ) So.. last evening i was going going through the military base south of NWAF and stumbled accorss a bandit waiting to kill me (he saw me approaching the place from a long distance but failed to shoot me earlier so now he was waiting at the top of the stairs in the main building). I have unloaded whole sks clip at him, moving behind the stairs at the same time - i don't think i hurt him bad, at least not as bad as he hit me - i had to bandage myself and while i was trying to load my rifle (didn't realize ammo was ruined) he got down the stairs and finished me before i managed to get closer with an axe. So, naturally, i had got the 'you are unconscious' message and prepared to respawn but here is what happened: i had regained consciousness almost instantly and the guy was nowhere to be found (well, i'm not sure he didn't run outside since the first thing i did was to hide in a room to patch myself up but he surely didn't disconnect/logout since i would still see him - 30 sec hadn't passed yet). Even assuming he ran away as soon as he finished me, w.o looting, how could i get up so fast?

Oh well, that might explain a bit, thanks. Still, it was weird for the other guy to vanish so quickly.
