You are doing everything right. I also noticed this issue today. The bug must have slipped in on the day of publish, before that, zombie battle was working just fine. Ayy, I knew after such a big refactoring some bugs will show up, but I was hoping for less severe ones :-/ Anyways, here is what I did: I published the pre-refactoring version here: http://humane-tiger.com/9dayz/ This version does not include the in-game editor (my goal for the Img27 Jam) - but zombie battles and most other things work just fine (can be played till the end). So if you want to explore the game world including fighting zombies, I recommend playing this version.
