Not worried about the characters life as this is dayz.

However I had Full colour,
My character stats said healthy yet I was 1 hit by a Zombie.

Check the logs and just review the damage dealt and ensure this is how you guys want it to happen.
Unsure if this was a bug or is just by design.
This is the first time I have had this 1 hit happen and thought it was odd so I have reported it like a good little tester.

I was at Green mountain and was crouch walking as there was a zombie in front of me.
I heard the zombie behind me scream out as it attacked, There is a chance it hit me twice but it managed to kill my character in two hits.

I had a pristine Drybag, I had a pristine M65 jacket and then I had a Hi Cap vest of unknown condition.

The characters name was Strelok on a New Zealand Private Hive server.
