No it is a bug that causes blurry vision. My lil dude is not sick, thirsty, hungry, poisoned, shot, stabed or bleeding after respawned. It does not happen all the time, and seems to only happen on logging in

same here, all is blurry until I click on video options. Disabling post processing prevents it from happing, but I kinda of like to know when my lil dude is about to die

I get the same thing. Everything is fine until I log out of a server where this happens http://steamcommunity.com/sharedfiles/filedetails/?id=206954214. the menus are fine and work normally but everything else is screwed. Restarting the game temporarily fixes it

From experience it can be done but it is far from easy, and there is a high chance that it will backfire. As far as Be4st's comment, I would love to see him do that IRL on youtube hilarity ensues

I accidently epi penned myself while chasing after a friend

I have been able to sneak up behind a zombie and not get noticed until I am almost on top of it. However I just spawned inside a house and a zombie comes crashing though the wall as soon as I went down stairs.

I then went to polina factory and ran up to the south wall with a zombie facing my direction, got spotted. Walked around the the east wall where I spotted another zombie (facing east-ish) with the wall and a shack between us, and was not spotted. Ran around like an idiot and never got noticed

Don't think antiperspirant will help (lol) considering the zombies will follow you into the water (how far I'm not sure but I am curious to find out) the only good thing is that they will walk under water, which to me is apt taking into accout that swimming is a learned skill that requires conscience effort
