when you enter the game asks you to move the files to a new folder. after the agreement, the transfer occurs, but writes that 0 bytes have been transferred. the operation is completed and asked to restart the game. nothing changes after a restart. if you enter the game after 24 hours, the request will be repeated, and all new worlds are not saved
