I've noticed that when using the "next action feature", it doesn't always take you to the unit or town that it should be. For instance: if you have "enemies at the hate" I'll often be taken to the correct shard, but a different city (one likely also with enemies at the gate, but not always), the icon will change to the firing icon, but there are no targets around the city that's being viewed, or none are valid (because they're out of range). Selecting the button again will then zoom over to the correct city.
