Hello
I've come across an issue with hordes of zombies disappearing. It happens when I've quit a game then come back to it a while later. The size of the hordes is 100+ and have grouped together due to a car alarm being triggered. I am on the latest build, only play single player and as far as I can remember the issue has only happened when on a user created map.
Now, for some, it wouldn't be a problem. Having a large group of zombie just vanish and not have to deal with them would make life in the world of Zomboid a little bit easier. For me though it doesn't sit right, I don't like to gain an advantage due to a glitch in a game even if had no control over it.
