I've noticed a couple instances wherein I sank ships in a convoy, only to have them respawn at the convoy's origin and race back into line. They also seem to be strangely focused; I was terrified to have a destroyer come running up on me out of nowhere, but it passed within a few hundred yards without so much as blinking his light (it was daylight, clear, surfaced). Has anyone else noticed this?
