Unfortunately, this case is not that rare. Map creators need to remember well: there should be at least 2, and preferably 3 free cells to disembark from the boat on the shore. And you also need to remember that when disembarking, the game perceives events as objects, and it is impossible to disembark in a cell with an event!
