Nukes don't cause wars / No grouped rocket damage

We're running an internal game to test out how effective certain weapons are.

My ally nuked London and of course the buildings were damaged, my 3 infantrymen stationed there died and 3 out of the 26 rockets that were stationed there were destroyed.

> However we did not go to war.

We remained at share map and I only found out about it the next day through clicking on London and noticing the damage.

I sent the remaining 23 (level 3) rockets to three of his cities.

10 towards Amsterdam

10 towards Essen

3 towards Cologne

> No damage to anything.

We watched them impact, we saw the explosion effect and we reloaded the game, however his cities are fine and continue to produce units. There was a newspaper clip about it but that was all.

A level 3 rocket has 60 power against buildings.

So, unless I am missing something somewhere, a group of 10 rockets should have 600 power, whilst his nuke only had 190 (first level bomber).

There were no fortresses nor planes guarding his cities (level 3 apparently can't be shot down anyway).
