Playing DarthMod as Spain. Carthago Nova region from turn 16 to 17 (winter 263BC, to summer 262BC) gets a strange "event" – farms get damaged, troops in the settlement lose a few men, troops in the region outside the settlement lose 15-20% of men, and movement in the region from then on gets twice slower (few turns later still slow).
No event shows up, this just happens.
Anyone know what this is?
