I played for a good half an hour or so, got a backpack, water bottle, some canned food, some rags and a gun that needed ammo and a magazine ,and decided to walk a while out of city limits in a safe place and then log out with the intent of coming back a few hours later when I have time on my hands to find a magazine and some ammo and let the journey begin.
Immediately on relog there is a zombie spawned on me and attacking me, I had no ammo for my gun so I start beating at it with my fists(I'm in the middle of nowhere, it's not easy to lose aggro) and eventually since the zombie seems to do more damage to me than me to it without an adequate weapon(I logged in the middle of nowhere for a reason dammit) I fall unconscious and we all know what happens after that.
This has happened to me about 3 times today every time with different inventory items, it pretty much just seems like there should be a safe zone around players logging triggering zombie spawn as to not have zombies spawn on top of them when they are nowhere near a built up area.
