Hi, thanks for the suggestions! Moving resources between storages is definitely something I thought about, but never implemented (also for the sake of simplicity). One thing you can do, is build a "drop-off" log shed next to a sawmill, where the sawer will the deposit their planks simply because it's the closest one. The jobs list is a very good idea! Will see if I can implement this.
Sorry the game crashed for you - if you have the crash log, or could tell me what exactly happened, I'd love to see it so I can try to fix the game.
Villagers do prefer walking on roads, but only in order to take the fastest route. The cost for a road-tile in the pahtfinding is about 0.75 that of a normal one. The more they prefer them, the slower the pathfinding gets, however.
