barbarian attack

Why allow a barbarian attack when your being attacked by another player. Pretty easy to include a check to see if the city is being attacked and cancel the games barbarian attack ?
You still only allow one casket and now that we are being attacked by barbarians it is beneficial to attack the barbarians before he attacks you which means you should be able to spend the casket ?

You won't be attacked by a barbarian camp in a holding which is being attacked by another player.
You can open one casket of a given type per day. For example, if you have caskets received for destroying different levels barbarian camps, you'll be able to open 1 casket from each camp.
