I've started a new world on the latest 0.H release candidate. In this one all the hordes seem to flee west instead of north, but the effect is the same. If you move north from the location the game is saved at you will see the zombies all stream to the left. The only thing that seems to break this is the presence of civilians, which pull the zombies out of their behavior when the agro onto the civilian.

I've noticed that when I first meet a horde, they all immediately start running together in a single direction. I don't find that this is consistently North, West, etc. It's often in the opposite direction that I approach them from.

By turning invisible and teleporting around I found that they seem to be locking on to the closest (distant) civilian from miles away and all rushing them. If I teleport to the center of a city, note the position of a civilian, and teleport next to them, from that perspective every zombie on the block is immediately running toward me.

Edit: I blacklisted HUMANs, invisi-teleported into a city, and the zombies were initially quite placid. Then the entire area seemed to start charging toward a migo at the north end of the city. It kind of seemed like it was zombies chasing the migo, then other zombies chasing those agitated zombies etc.

Edit2: No... there's some real problem going on. I just followed a feral cop about 30 overmap tiles west with no clear goal. He smashed through windows, went around buildings, always desperate to head into the west. He was originally chasing a fox, but he lost sight of it and just kept going. Attaching his json in case it helps.
