Do fish run out like the farming field. And how come my field run out so fast and come back so slow. Last thing... is there another way to get Master Builder faster than fixing huts cause its taking a long time to get one of my villiger to become master builder for the last puzzle.

The farm has only a certain amount of food with each crop, so if you have a lot of farmers harvesting the crops, it will be empty sooner. The ocean never runs out of fish!

Once all of the construction puzzles are complete, fixing huts is the only way for your villagers to gain construction skill. It does take awhile.
