Thanks for the reply. So far I've only used fists and electric truncheon and there doesn't appear to be a pattern.
I messed up my stealth in the Headboys fortress in the garden district and had to fight the three guarding the gate in hand to hand combat. I returned sometime later to find them all deceased.
Likewise the first guy who attacks you in the first safe house was dead when I returned.
None of my non-lethal choak-hold victims has died. They all get back up and resume their patrols.
As I've stated, everyone who was knocked out without the choakhold has been first knocked out then been found dead upon my return.
I'm not sure if the game was programmed this way, but any Wellies who happen upon an unconscious body talk like the victim is already dead. Whether or not this is a bug, I'm hoping the Developers will eventually allow unconscious victims to be awakened by their comrades, or at least have their comrades talk like they're unconscious and not dead.
Thank you so much for the reply. You and your team seem genuinely concerned about fixing bugs and I'm grateful.
