The game crashed just after a carpenter finished an eldritch artifact at a workbench consisting of meat, grapes, and maize... Crash Dump and save game is added here, for whatever the save might matter, not sure if it is easily reproducible, however there you have it.
At the time I was not on the experimental version, so it would be the version that is currently on Steam. I have since changed to the experimental version, and have yet to get the Mad Carpenter event.
I love the mad carpenter event, I have had 4 so far, 1 iron oven, 1 steam oven, 1 rare painting and a stone alter, I got the iron oven pretty early in the game which helped so much with increasing my food supply quickly.
