This is a little hard to explain. Four goblins appeared on the map, one “grabber” and three escorts. The one grabber ran into my base and was dispatched immediately but the other three hung back in their “ready” pose.
I noticed this when they were about 60 - 80 voxels from my footman who was doing the same “ready” wardance. The goblins approached a few voxels at a time with both groups wardancing the whole time. The problem, there is a wall between them and they would not be able to see each other.
Now you can see that they are still squaring off at each other only a few voxels from the wall, but they would not be able to see each other. The ready pose is wrong for someone who can’t see his enemy.
Further, my farmer and villagers react with terror when they get close to the wall, but of course, they are in no danger. Below is a shot of them running in terror.
