So, when I saved, exited the game and then when I continued the run, all the zombies in the 360 view just full on disappeared. For a test, I sprinted a bit further away from where I logged out, there were only very small amount of them (this was in west point). This happened to me a few times before. I've got quite a few mods enabled, yet no idea on which one might cause it, or if mods are even associated with this bug.
