Thanks for the clear up. I could have sworn it was some "spawning" as I had shot a couple of bullets around my safehouse to make sure no zeds came, yet 36 hours later. My safehouse was almost overrun, I came back to every window being attacked by zombies and several small groups of zombies in the vicinity. I will adapt to these changes, the problem is I play this game in an almost OCD manner. I hate leaving any zombie alive in the area around my house. These new changes make it really hard to do so, especially if I have to do a looting trip that will take me a few days to accomplish. At the same time I agree the difficulty was all frontloaded before, once you had a decently fortified base, you could survive there forever without any worry of hordes coming down unto you. But this feels a bit gamey and I hope they tweak slightly. PS : Yes I realize there is sandbox mode. Dozens of people have noted that already, simply trying to give a bit of feedback.
