[Ciznit (DayZ) 3]

Date/Time: Last night (5/23) and tonight (5/24)

What happened: Last night my friends and I we're on a server when it crashed. We log on a different server and our progress is reset to when we first got on the original server. Also, we have copies of ourselves standing next to us which we can kill. We decide to log off for the night.

Today: We log back and we are all on the coast, but with our gear. Two of us have random ailments (bleeding etc.) that we didn't log out with. All of our health is reset to 12000. Over the next couple of hours, anytime someone logs off their health is reset to something higher than it actually is, usually 12000. One player manages to bleed out down to -6000 health (he isn't taking damage from anything else). He logs off and comes back on and his health jumps to 5500. Later on in the night him and another one of us are killed, so this bug wasn't a permanent thing.

Where you were: Last night - SW of Stary Sobor, Today beginning - on the coast, Today at -6000 blood - outside electro power plant.

What you were doing: Last night - travelling/checking deer stands, Today beginning - starting to play, Today at -6000 - in a fight with another survivor.
