It was the same with Build 32. But I can remember that in older Builds Zombies didnt had this behavior. Zombies will attack doors, windows ect. without a reason, without that you do a Sound. That just doesnt feel right. I could also see it when lurking some big zombie hordes through westpoint. The last Zeds in the horde will stop following me after some time and will just go attack some random doors and windows without a reason. There should be at least a option in Sandbox options to deactivate this behavior. I get it that this make the game much more difficult for survival but we should have the option to decide if we want to play with this "unrealistically" behavior. ( In movie terms, like Walking Dead ect. ) For Example i like to have to play with much more Zombies than normal but have them all set to slow moving and that they dont take much hits ( but do normal damage ) Also I allow them to build Hordes up to 500 but have deactivated Respawn and give them hearing up to 500 ( meters ? ) This give me a much better "Immersion" ( feeling more like TWD or other Zombie Films/Serial ) But if they gonna just without a reason attack doors and windows, even when I am sneaking through my Safehouse on second floor, this immersion is gone, because in this moment i know that its not real Sandbox, its just a script made to make the game harder for me. Also in Build 33. I am very Sure that Zombie Migration is Script-Leaded to Player location. In my last game i had respawn deactivated but migration on normal, my Base was on the Gas Station North-East from West Point and after I had killed there over 2000 Zombies i gave up, every new day were there 4 new zombies for every 1 zombie i had killed with axes and baseball bats ( so no loud sounds from me ) I even had Meta Events and could see how the Zombies ran away to South because of Meta Shots, but the next day they came all back. Please give us the Option to change Zombie behavior in Sandbox, so that they will not attack without a reason Windows, Doors and builded Walls. Just put that option under Zombie Navigation skills maybe. As an extra, a option to put off Meta events in Sandbox would be also handy. I
