However, around day 39 some really weird stuff started happening, it started with my oxygen system not working, so I had to surface and open the main induction valve for the rest of the patrol, and around day 45, I was teleported from the coast of Argentina to the coast of West Africa. All this leads me to believe the USS Harrison is cursed.
