I had that happen once when I saved near a convoy. I was underwater and I dropped to what I thought was a safe depth and saved. I blew an attack so I quit and relaunched and yeah, my PC decided that I was too close to the convoy and it did not feel like rendering all the ships, so, back outside to desktop I go. I never felt the sting of that kind of failure often, just every now and then.
