Shields

When a Capital's defending army dies, there is a chance that Gold will be stolen from the Capital's City Hall, and that capital then gets a temporary shield. If any settlement loses its relic, then that settlement gets a shield.

If a policy level gets knocked down by a wagon stealing Gold from a Capital, the city then gets a temporary immunity shield for 24 hours. The duration of the shield remains the same regardless of how many policies get knocked down. [what if someone else attacks for that immunity]. Armies that were already on its way to attack the city before it got shielded will be unable to attack the city.
