Well, good news. I gave Scipii Cyrene and that accompanied with the occasional save/reload can really kick-start the Roman factions into action.

It seems Brutii and Scipii have trouble with the initial order for seabound invasions, but a quick save/reload seems to trigger them into action. If you see stacks hanging around the coastline doing little, possibly repeatedly getting on and off ships without apparent purpose or progress, then a quick save/reload seems to solve the stagnation.

Good work for noticing that player 1.

Now if we can only find a cure for the AI not using pila, etc, before attacking...
