Cabin Riches V2

First time attempt at an escape room. V2 solves a few puzzle skips and bugs. A family relative has recently passed away, however before their passing you were the last to visit them on their death bed. They told you that over the course of their 25 years as a bank manager they had been stealing money silver, and gold. Slowly bit by bit over the 25 years they had amassed a fortune, and to keep that fortune safe it was hidden within their cabin. Unable to spend the mass wealth themselves they tell you of three keys that were hidden to keep it safe. Could it just the rambling of someone who was knocking on death door or perhaps a treasure hunt for the ages?
