Unmanageable ship (Assassin's Creed: Rogue)

This situation, completed 85% of the total, moved from one point to another by using quick move (was too lazy to swim from one to the other), when moved to one Fort was left to steer the ship, but lost all the auxiliary graph, i.e., map, help in managing money, generally clean the screen with the ship and textures. The ship sails itself, the keyboard does not work (Esc only), operate it cannot. Tried to go back to the last memory, there is also ship and exactly the same problem. What could be the problem?

P. S. while the ship sailed by itself, then got caught in a storm, oddly enough, but it was at this point returned to the office, no card was nothing, but you can manage it.
