Hi, if there is only one region with population nearby 7 zombies or more...do they all go to that region because they lack another target? (not 3 2 1 ...)
i think the rules are quiet clear with this but it seems a little bit strange in our last sessions...
You have interpreted the rules perfectly. If regions do not have a population die present they will not attract zombies to those regions. Instead zombies will mull about in the region in which they occupy and will not move at all. However, if an adjacent region has a population die they will all be attracted and migrate to that one region. (Ie. no 3,2,1).
Thanks for the question,
