As the title says you are able to cast negative spells like Gluttony, Sloth and Ingnorance on a Neutral (and even Aliied) city. This should either be impossible, or result in war.

The same thing is possible for Flood, Earthquake and Volcano.

Furthermore, the interface gives no information on negative city spells cast. Neither are thei reporten when clicking on the city nor does the casters enchantment list tell which city is affected. Graphical Feedback on the main map is also not present.
