Efficient Citizen Logic Mod upgrades the movement and working AI for citizens in MineColonies. It stops workers from getting stuck on blocks, ignoring pathways, or wasting time across the town. Citizens follow built roads, eat meals close to their workplace, and use minecart rails properly. Colony builders can also adjust housing beds and workplace sizes much better with these changes.

Features:
Smarter Citizen Movement:
- Citizens stick to built roads and paths instead of wandering through random terrain.
- Pathfinding handles ladders, stairs, and steep hills with fewer falls and jumps.
- Stuck workers automatically find alternative routes or reset position when blocked.
- Citizens use minecart rails properly and dismount cleanly at detector rail stations.
Better Work and Hunger Logic:
- Workers eat food from their personal inventory or workplace before walking across town to a restaurant.
- Farmers work with modded crops, rotate field plantings, and harvest honey without angering bees.
- Lumberjacks gather all wood and sapling drops from tall tree leaves.
- Smelters manage multiple furnaces at once and share tasks between multiple hired workers.
- Couriers bundle multiple pickup and delivery orders into single trips.
- Animals stay safely inside their fences and pens.
Colony Scaling and Health:
- Houses hold more beds per building level so you can build larger apartment setups.
- Workplaces like smelters and courier huts hire extra workers as the building level goes up.
- Injured guards and townspeople seek out hospital beds when hurt.
- Doctors take emergency cases and treat illnesses much faster.
