I'm playing as Seleucids, and a few ingame decades I helped Carthage by transfering their quite large armies from Africa to Iberia, where they were loosing badly do Lusitans. They defeated them, and pushed them to one settlement, even expanding into Gaul. Later, I got a land border with them and they started sending full stacks to Cyrenaica regulary. I just moved them back. However, some time ago stacks stopped coming. I turned fow off and checked them. They had no large armies in Africa and Lusitans were making a comeback in Iberia.

I checked their ships, and they had almost three fullstacks on them, just standing near the shore. Since then more than 10 turns passed but those armies are still on ships. Lusitans have meanwhile conquered all but three Carthagian cities, and one of them is being besieged. Why won't they disembark all those troops? Can I help them somehow?

On a brighter side, they showed some remarkable intelligence in this campaign. When Lusitan reconquest started they were at war with KH, who had Emporion and Massylia in the theater. When Lusitans made some serious inroads, even gaining a border with KH, Carthage and Greeks made truce. A few turns later they became allies. Quite intelligent for AI.

I'm playing on M/M, year is 162bc.
