I am playing as Rome and the Carthaginians hold Corsica. At one point, a large Keltoi rebel force with a leader appeared on the island, to which Carthage reacted by sending an army to meet them. However, neither army ever attacked but instead keep building up their forces in the countryside. It must have been going on for something like a hundred turns. At the moment Carthaginians have a full stack and the Keltoi two full stacks with multiple leaders. They seem to be engaged in a never-ending arms race, and it will already at this point take considerable effort to take the island assuming that both will be hostile to us. Have you had experience with something similar and do you know of a way to break the deadlock?
