I am not sure if it was that guy. Could be, but for me it rather looked as if he walked through some wall from some of teh buildings (or, maybe, got duped and teleported from somewhere,. much like the sledgehammer tribal woman from the shack with sewer hatch that disappeared in the same raid?) And why that guy is outside the town area all the time?
Btw, tried to play as a melee fighter and it is very annoying that all critters are running away when low on HP. Hard to kill most of them without using firearms or being lucky with critical hits / stuns to finish them off before they get low enough HP to start running away. I don't remember enemies in teh original game running away so often (if at all), uless they were blinded (crippled after a targeted eye shot). I only remember party members running away if ordered to do so on certain health threshold. Maybe keep it only for small / ranged / intelligent critters, like rats, silver geckos dogs (if/when you'll add them), kids and peasants (maybe female raiders too?) but primitive creatures like ants and scorpions, fierce ones like golden geckos and mad ones like raiders won't run away? Or make it so the last critter in a squad / pack would try to run away (like stray dog packs would flee if you attack the pack leader and make it scared and running away), but until there are many enemies in the group (like a bunch of raiders or geckos) they'll stay confident enough to keep attacking from behind until you are outnumbered by their bretheren?
