ships won't fire at enemy planet due to treaty!

[Dizzy]

Ok, probably a dumb noob Q, but I orbited/attacked an enemy planet with 20m pop. and 3 facilities and set it on Strategic combat and watched as my 5 ships did nothing.

I attacked again tactically and to my surprise, my missile boats did not fire at the enemy planet. Why?

Do we now need specific planet bombs to do this? Are missiles ship to ship now only?

I must've missed the memo.

EDIT: I have a treaty with another race stating neither of us may bombard planets. hehehe. Got to watch those damned treaty details closer!
