Hi,
The clues you provide say that I need a master builder for puzzle number 12. I have completed the first 11 puzzles but have never had a master builder. I currently have 3 that are adept, 2 of which are close to master level. Do they gain skills by repairing the hut, or do I need to start over? By the way, I purchased village sim 2 days before the update, so I am ready to update as soon as I start over. I've have 3 adept doctors go missing as they were close to being masters. Never had a master doctor yet. Very frustrating. I don't think they disappeared during burials, but I do believe I moved them when someone was honoring the dead.

It's easy to complete the game and never have a Master Builder, especially if you have a lot of villagers working on the construction projects. There is only just so much work to go around. Unfortunately, in v1.0 the only way to train a builder after all of the construction puzzles are completed is to hope for an Island Event that washes more debris onto the beach. In v1.1 you can train builders anytime by having them fix the huts that they built.

The bug that causes villager disappearances has also been corrected in v1.1.
