RESOLVED: Bug with alliances

Again, considering this as a bug, so it's here.
And have nothing to do with other topics about alliances.

I am in game, have 1 ally (not verbal one), my capital is taken.
We join our forces and retake my cap, still I am lost.
Don't you think, that there have be an option to pass Capitals (not all towns) to your Ally, or, consider this as "friendly forces retake your Capital, so you are not lose"

Well what has happened in previous games is that we coult "float" the capital. where two allies swich who controls the capital until the other ally whoose capital it is can get a unit over there. the onlydificulty is rembering when your susposed to switch and the # of turns for defeat.
