Zombie spawns seem to be even worse now

[ZehMatt]

Zombies spawning at locations where I just came from was already annoying in earlier versions, now I had the situation where a feral zombie literally spawned right before my eyes and destroyed me on the first night on my first run to test A21. I don't really enjoy always making a mod to have a somewhat more realistic approach to where zombies come from, even something like a minimum distance to the player would help this a lot already. I'm not sure if this is a regression or not but I recall that in A19 it at least checked if the spawn would be in line of sight of the player. Also it would be great if there is something like cool-down for areas where the player just travelled so that when I turn a corner and come back there won't be suddenly a zombie waiting for me, this is pretty immersion breaking in my opinion. For a zombie game this always annoyed me that such fundamental system seems to be ignored somehow or is not properly tested, I can't really say and that is just my opinion on that. I do plan on porting 

to A21 but I also want to start this from scratch so it will probably take a while, but I shouldn't be also the one having to do that.
