I think I got Zombies to run into/inside some buildings. The "problem", I guess, is that Zombie AI and line-of-sight is very strict somehow, especially when paired up with the "Zombies hear/see 50% less through walls" feature. Once you run inside buildings and take a turn you're out of line-of-sight and the Zombies have a hard time seeing/hearing you, thus lose aggro on you. The barn you can run straight through, with doors that open outward, seems especially easy to lose aggro in. Hatchet still needs reloading for me too. Also for some reason in about 8 hours of gameplay I have been completely unable to find a Box of Matches...could just be a streak of bad luck, I guess. I have also not found any bear traps. Has anyone? I'm seeing....."strange" behavior from Zombies at times. Feels like not all solid looking walls are as solid as they look and some flimsy looking walls are like ten feet of concrete. Zombies standing in small sheds can illustrate this well. They will aggro, then go passive, then aggro, then go passive over and over if you are close.
