New Gameplay:
Remove Mammoth's watering ability; add "Expedition" ability; introduce new irrigation tech points.
Mammoths and cattle both compete for farmland work slots, causing AI confusion in prioritizing field tasks.
Mammoth New Ability: Boost movement speed on world map.
Expedition Enables cross-continental East-West communication. This ability can be enhanced through selective breeding tech.
Irrigation Watering: Players can water crops without waiting for mammoths. With buckets available to all villagers, actual efficiency exceeds mammoth-based watering, verified via my own playtesting.
Bugs:
Released slaves continue occupying slave room slots after joining the tribe. Must demolish slave room to release bed slots.
Berries now function as cooking ingredients and increase Intelligence.
Caravans spawning at night: 3 members build campfires while the other 3 sleep on the spot.
Incorrect occlusion relationship between caravans and settlements on world map, causing selection difficulties.
