one thing i noticed today, regarding road flares etc... Well first of all i found a tractor and ran it into a tree near the center of a village, well it blew up and lit up the area (night time), the near by zombies just ignored it and continued walking the direction there was (away from the tractor) so I went prone and went away from the blazing tractor and found cover, I then lite a road flare and threw it close to a zombie again he kept walking as if it was not even there... is this a bug because I have thrown road flares and glowsticks before and the zombies dont interact with them at all.. even tried smoke granades on a day time and again no interaction, this has happened every time I tried to distract them and found it does the same on every server I go on.. any ideas on this?

Well it beats my 1st time of playing (about 2 months ago), I started with the map (online one) on my 2nd monitor and searched loads of medium value houses only finding empty cans. I spent 2 hours doing this.. then I went to electro. where it seemed that every zomby could see me from 2 miles away as they all came running for me.. so I ran away and tried the houses in the closest village, again crawling along as every zomby would see me from a range of around 600 away from the village, eventually after alot of running away and coming back i made it into the village, I only found empty can in every house i went into apart from one and there I found some glow sticks and a road flare.. Then I thought I would try a dear stand as I have tried houses with nothing useful to pick up... so I went to a dear stand nothing again.. but there was a small hut at the side of the road not far from me surrounded by zombies.. hmm to distract them while I have look to try to pick something up... So I threw a glow stick, hmm the zombies did not batter a eye lid at it, so I threw a road flare.... That had no effect on the zombies either... so I pressed escape and disabled the mod and went to play amar 2 OA... Now I am thinking give it another go (2nd time of playing the game)... Dont know if it was just a bug with the no pickups or it was the server (public server) i dont know wich one it was ( it was a couple of months ago....) Is it normal for zombies to be able to see you for such large distances? even at day time walking (not running)?
