I put up a wooden door, hung a lock on it, made a key, and closed it. After I went for resources, while chopping down trees, a bear came up from behind and killed me and the key remained in the corpse. Then he did not leave there, and I was dying and dying in attempts to take the key. The key has disappeared and now I cannot get into the house, I can only go out by jumping off the roof (there is a sunbed in the house). Actually, how to make a new key and get into the house, the walls are stone, they cannot be broken, and the wooden door 200 hp also cannot be broken, axes break quickly. There are a lot of things in the house (I got it at the factory).
