(PS4) Moose/Goose boss will spawn in, and if the Moose is not killed before it lays its egg the game will crash with an error screen. Only way I avoid this bug is to locate the Moose and defeat it.
Wait until spring until Moose/Goose boss spawns in, if you locate the boss or not the error will still occur. Once Moose/Goose is located wait until it lays egg and the (crash) error screen will appear. (PS4 slim)
